or There is a line that includes the point (1, 2) and has a slope of 7 . What is its equation in slop -intercept form?

Answer 1

the slope-intercept form looks like y=mx+b ups know slope is 7, which is m.

so you have y = 7x +b

You know a point, x=1,y=2, plug them in the equation, you have 2 = 7 x 1 +b

so b = -5.

ready for the answer?

y = 7 x -5
