Question

Write an equation of a line in slope intercept for that is PARALLEL to y = 3x+6 and passes through the point (-10,2.5) I finally understand slope intercept form until this threw me off! Please help!

Answer 1

It's the almost the same thing, the only difference is they already give you the slope. Parallel meaning the same as that equation.

Answer 2

Parallel lines have the same slope..

y = 3x + 6

So the slope here is 3..

We can plug the slope and the point into point-slope form:

\(y - y_1 = m(x - x_1)\)

Where \(y_1\) is the y-value of the point, \(x_1\) is the x-value of the point, and \(m\) is the slope.

So we have:

\(y - 2.5 = 3(x +10)\)

Answer 3

Simplify and you'll get your answer in slope-intercept form.

Start by distributing 3 into the parenthesis.

Answer 4

thank you! @iGreen.

Answer 5

No problem.

Answer 6

so would I do the same thing for a question that is perpendicular?

Answer 7

Answer 9

Perpendicular means it's the negative reciprocal of the original so no.
