Question

Which of the following can find the slope of a line passing through the points (-4,8) and (x,3)?

Answer 1

Explanation:

This two point should be pass in the point (0,0)

So, we will write it like this :

y2 - y1 over X2 - X1 :-

8-0 over -4-0 = -2

then we will write it like that to find what is X :

3-0 over X-0 = 3/X

we know that the answer is -2 So, the 3/X should be equal to -2

So, X = -1.5
