Answer:
y =3x + 5
Step-by-step explanation:
The slope intercept form of an equation is expressed as;
y = mx+c
m is the slope
c is the intercept
Get the intercept
Substitute m = 3 and (-2,-1) into y = mx+c
-1 = 3(-2)+c
-1 = -6 + c
c = -1+6
c = 5
Get the equation.
Recall that y = mx+c
y =3x + 5
This gives the required equation
