Answer:
y = 3x + 4
Step-by-step explanation:
I guess the question should be : find the equation of the line that passes through ( -1 , 1)
with slope 3
The equation of a line
y = mx + c
Step 1 : sub slope into the equation
m = 3
y = 3x + c
Step2: sub the point into the equation
y = 3x + c
( -1 , 1)
y = 1
x = -1
1 = 3(-1) + c
1 = -3 + c
1 + 3 = c
4 = c
c = 4
Step 3: sub c into the equation
y = 3x + c
y = 3x + 4
