I really need help understanding this! 1. Which two points lie on a line with slope 2/3? (2, 0) and (3,0) (3, –4) and (1, 2) (0, 0) and (2, 3) (–3, 2) and (0, 4) 2. What is the slope of the line that passes through the given points? (6, –1) and (–3, –1) undefined 0 – 2/3 – 3/2 4. Write the equation in slope-intercept form. What are the slope and y-intercept? 3/4x + 4/5y = 4 y = 15/16x + 5; slope: 5; y-intcerpt: 15/16 y = 15/16x – 5; slope: 15/16 : y-intercept: –5 y = –15/16x – 5; slope: –15/16; y-intercept: –5 y = –15/16x + 5; slope: –15/16; y-intercept: 5

    1. Which two points lie on a line with slope 2/3? use: m=(y2-y1)/(x2-x1) and plug in m which is slope and see which of the choices satisfies the equation 2/3=(y2-y1)/(x2-x1) It is (–3, 2) and (0, 4) (2-4)/(-3-0)=-2/-3=2/3 :)

    All you have to do for q 1 is use the slope formula which is. m=(y2-y1)/(x2-x1) where m is slope and it will be 2/3 y2 is 2nd y y1 is first y x2 is 2nd x x1 is 1st x and just start pluging in.

    ook :D 2. What is the slope of the line that passes through the given points? (6, –1) and (–3, –1) you use the same formula y2 is 2nd y y1 is first y x2 is 2nd x x1 is 1st x |dw:1354601772235:dw|

    4. Write the equation in slope-intercept form. What are the slope and y-intercept? 3/4x + 4/5y = 4 I think you skipped number 3. But the above is just solve for y and you effectively put it in y intercept form.

    simply solve for y 3/4x + 4/5y = 4 4/5y = 4-3/4x 4/5y = 5/4*(4-3/4x) y=5/4*(4-3/4x) y = -(15/16)*x+5 distriute 5/4 and rearrange

    Just take it slow and read carefully :D All things are very simple that way.
