find the value of y

Question

find the value of y so that the line through the given points has the given slope (5,y)(1,-3) slope 5/4

Answer 1

Jay,

You just need to set up the standard slope equation with y instead of a number and solve for it.

 

m = (y₂ - y₁)/(x₂ - x₁)

 

5/4 = (-3 - y)/(1 - 5)

5/4 = (-3 - y)/(-4)

-5 = -3 - y

-2 = -y

2 = y
