SOLUTION: If you have two points (2,y) and (5,4) and the given slope is -7. How do you find what y is?

Hi,

  

*Note:  the slope tells us how the points on the line relate to one another

slope of -7 Or -7/1 tells us as that: as y decreases by 7, x increases by 1

Or as y increases by 7, x decreases by 1.

Pt(5,4)

Pt(2,y) x has decreased by 3       

-7/1 = 21/-3)  y has increased by 21

Pt(2,25) would be that other point

y = 25
