Question

Write an equation for the line that has a slope of 4 and goes through the point (-2,-5)

Answer 1

Your answer would be y = 4x + 3.

Since we are already given the slope, we just need to find the y-intercept. We can do this by writing the equation as y = 4x + b, and then substituting in the coordinates that we are given. This gives us:

-5 = (4 × -2) + b

-5 = -8 + b

b = 3

So now we can write the whole equation as y = 4x + 3.

I hope this helps!
