(-2,2) and (-1,y) ; slope:-3

Question

Find the value of x or y so that the line through the points has the given slope.

Answer 1

per given values, we know y = -3x + b

 

replace (x,y) with dot (-2,2), you get 2 = -3*(-2) +b, so b = -4

so y = -3x -4

 

for dot (-1,y), y=-3(-1) -4 = -1

 

so (-1,-1)
