    The answer is D. I know this because all you have to do is use a calculator, and fill in the x and y values in the equation from your answers, and see which one adds upp..(:

    in an ordered pair, the first number is the value of x and the second one is y, so, just put the value of x and y and see which gets u 5 ..... *sshhh* its the last one :P

    Okay, so when you are doing slope, you use rise over run. Rise is the up or down along the grid, and run is side to side across the grid. So you will measure you r rise )Up or down motion) as opposed to your run(Side to side motion) count how many there are and thats your answer

    2x-3y=-12, or, -3y=-2x-12 pr. 3y=2x+12 or, y=(2x+12)/3 now, find that value of x for which y would be 0. in this case, it is -6.... (-12+12)/3=0 similaryl, 2x=3y-12 or, x=(3y-12)/2 for y=4, x=0....so the correct answer is B,

    Q.9---what is the relationship between these two lines: 3x+6y=8 y=2x-8 as i said, try to transform the equation into y=mx+b form, the second one is already done...lets go with the first one. 3x+6y=8 or, 6y=-3x+8 or, y= -3/6.x + 8/6 or, y= -1/2.x + 4/3 what u wanna look at now is the part with x (the 'm' part in y=mx+b) and in this case it is -1/2 (u have to take it with the sign)....it is the 'slope' in case of y=2x-8 slope, m is 2, right? whats the relationship between 2 and -1/2?? -1/2 is the reciprocal of 2 with the opposite sign (u know what a reciprocal fraction is, right?) when one straight line has a reciprocal slope with the opposite sign in respect to another straight line, they are perpendicular to each other. i hope this explains.

    Q. which has a slope of 5 and y intercept of -3? all of these equations are in intercept form. ( y=mx+b as i said) m is the slope b is the y intercept so what u are looking for is an equation that has m=5, b=-3 look for it!!

    Q. which one is graph of inequality y<2x+3 the shaded part is the part that denotes the inequality, i guess u already know that. if there's a straight line between the shaded part and the white part, there should be a = sign in the equation....you dont see any '=' in the equation, do you? in that case, you can just eliminate B. now, the best way is to take a (x,y) pair. and the easiest to work with is the (0.0) pair. substitute the values of x and y here. 0<2.0+3 or, 0<3 which is totally true (0,0) lies in the shaded part of C, so C is the answer. sometimes, you might also have to check some other pairs (1,1) or something else too, just to be sure. if you'r wondering whether A is correct or not, take a point that lies in the shaded part, lets say it is (-2,4) (its in the shaded part, check out) 4<2.(-2)+3 or, 4<-4+3 or, 4<-1 apparently, 4 can never be less than -1. so there you go...its not A, not B...its C.

    i believe we already worked on 5 and 6 a while ago...check. Q.7---a line that passes through (-2,1) and has a slope of 5. if my earlier explanations were clear enough, i believe you already know that only option A and B has a slope of 3 now, check them with the pair (-2,1). you wanna put x=-2 and y=1 and see if its true. for A, (1+1)=3(-2+2) or, 2=0 TOTALLY WRONG! for B, (1-1)=3(-2+2) or 0=0 there you go!! Q.8: what is the slope of the line parallel to 2x-3y=6 find the slope first. -3y=-2x+6 or, 3y=2x-6 or, y=2/3.x-2 so, the slope is 2/3, right?? remember what i told you a while ago? perpendicular lines have a reciprocal and opposite signed slope..... in case of parallel lines, they have the same slope. so, the answer is 2/3..
