Question

Through: (-1,1) slope=3

Answer 1

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
