M=3 and through (2, -1) in slope-intercept

y = 3x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 3, then

y = 3x + c ← is the partial equation

To find c substitute (2, - 1) into the partial equation

- 1 = 6 + c ⇒ c = - 1 - 6 = - 7

y = 3x - 7 ← equation of line

correct me if i'm wrong and if it is i'm truly sorry.
