There is a line that includes the point (2, 9) and has a slope of 7 . What is its equation in slope-intercept form?

Answer 1

Hi Alicia!

Note that the slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Plug in the slope for m and the given coordinate for x and y:

9 = (7)(2) + b

9 = 14 + b

b = -5

y = 7x - 5
