Question

FIND THE ANSWER IS SLOPE-INTERCEPT AND STANDARD FORM!

perpendicular to 3x+4y=13 and through (2,7)

Answer 1

would 3x+4y=13 be standard form? (Ax+By=C)

Answer 2

Yes.

Answer 3

so then what would i have to plug in to get the slpe-intercept?

Answer 4

Slope intercept form: \(\large y=mx+b\)

Answer 5

You want to isolate the y on one side and your x's and constants on the other side.

Answer 6

so: y= -3/4x + 13/4

Answer 7

To accomplish this, subtract -3x from both sides and then divide the whole fraction on the RHS by 4. You will have isolated your y.

Answer 8

Great job! You got it :)

Answer 9

thanks!
