    4x + y = 5 when x=0. y=? (0,y) 4(0) + y = 5 0 + y = 5 y = 5 (0,5) when y = 0 x = ? (x,0) 4x + y = 5 4x + 0 = 5 4x = 5 x = 5/4 (5/4 , 0) plot the points, and since they are lines ... conect the dots

    any 2 points will work, just have to find them. x=0 the y=0 tends to be the easiest way tho

    \[y = -4x +5\]\[3x -7y=27\]\[3x -7(-4x +5)=27\]\[x =2\]\[y =-4(2)+5\]\[y = \]\[P(2, -3)\]
