Question

Find the equation of the line that is parallel to the line y=-3x-7 and passes through the point (1,2). Write an equation in slop intercept form

Answer 1

y=-3x+5

Explanation:

y=-3x-7

slope is -3

parallel lines have the same steepness, they have the same slope. The slopes are equal.

y-y1=m(x-x1)

y-2=-3(x-1)

y-2=-3x+3

y=-3x+3+2

y=-3x+5
