Question

Write the equation for a line that passes through (4,-1) and has a slope of 5

Answer 1

y = 5x - 21

Explanation:

Since we already know the slope, all we need to do is plug the values of x and y into the equation.

y = 5x + b

-1 = 5(4) + b

-1 = 20 + b

-21 = b

The equation is y = 5x - 21.
