Answer:

The answer to your question is y = 3x + 2

Explanation:

Data

Point (1, 5)

Passes through (2, 1) and (0, -5)

Process

1.- Calculate the slope of the parallel line

Formula

m = (y2 - y1)/(x2 - x1)

-Substitution

m = (-5 - 1)/ (0 - 2)

-Simplification

m = -6/-2

-Result

m = 3

As both lines are parallel, the slope is the same.

2.- Calculate the equation of the line

Formula

y - y1 = m(x - x1)

-Substitution

(y - 5) = 3(x - 1)

-Simplification

y - 5 = 3x - 3

-Solve for y

y = 3x - 3 + 5

y = 3x + 2
