The coordinates of point a are 50 units of x and 70 units of y. the coordinates of point b are 46 units of x and 76 units of y. with x on the horizontal axis and y on the vertical axis, the slope of the line between points a and b is

The slope is given by

... m = ∆y/∆x = (76 -70)/(46 -50) = 6/-4 = -3/2

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
