Question

Line A's equation is y = 3x + 11. Line B is parallel to Line A and and goes through

the point (-1,5). Write the equation for Line B in slope-intercept form.

Answer 1

y = 3x + 8

Explanation:

line a: y = 3x + 11

This means that the slope is 3 and the y intercept is 11.

(-1,5)

line b: y = 3x + b <--- we need to solve for b and plug in the numbers from the coordinates

Just plug in the numbers!

5 = 3(-1) + b

5 = -3 + b

5 + 3 = b

8 = b

The y intercept is b! So the equation is:

y = 3x + 8
