Question

Find the equation of a line passing through the point (1, 1) and having a slope of 3.

Select the appropriate response:
A) y = 2x
B) y = 3x −3
C) y = 3x −2

help please!

Answer 1

Answer:

The answer to your question is the letter c) y = 3x - 2

Step-by-step explanation:

Data

P (1, 1)

slope = m = 3

Process

Just look for the slope-point equation of the line and substitute the values.

Formula

              y - y1 = m(x - x1)

-Substitution

               y - 1 = 3(x - 1)

-Expand

              y - 1 = 3x - 3

-Add 1 in both sides

              y - 1 + 1 = 3x - 3 + 1

-Simplify

              y = 3x - 2
