Question

What is the equation of a line with a slope of ​3​ and a point (3, 1) on the line?

Express the equation in the form of y=mx+b where m is the slope and b is the y-intercept.



Enter your answer in the box.

Answer 1

The equation of the line would be y = 3x - 8

Explanation:

To find any equation when you have the slope and a point, start with point-slope form and then solve for y.

y - y1 = m(x - x1)

y - 1 = 3(x - 3)

y - 1 = 3x - 9

y = 3x - 8
