Question

Can someone Explain step-by-step how to solve this?




Find the equation of the perpendicular line to each of the following that passes through the point indicated.
4x + 5y = - 40 passing through the point (-1, 3)

Answer 1

First put the first line into slope-intercept form. Do you know how to do that?

Answer 2

isnt it y = MX + B?

Answer 3

so it would be y = -4/5X - 8?

Answer 4

are their any options?

Answer 5

y = -4/5x + 8 soo yea your right!(:

Answer 6

Options like answers?
Yeah
-5x + 4y = 17

5x + 4y = -17

5x - 4y = -17

5x + 4y = 17

Answer 7

oh then so you have to turn it into standard form

Answer 8

So how do i put it into Standard?

Answer 9

Ax + By = C

Answer 10

I got 4x + 5y = -40....I moved over the 4/5th to the left side then multiplied everything by 5 to get rid of the fraction...What did i do wrong? :/

Answer 11

i really don't know i wish i could help you, try asking this question again and do you have flvs?

Answer 12

florida virtual school? because this question looked familiar but im guessing i forgot how to do this.. i took flvs last year thats why

Answer 13

oh haha well their both virtual schools. Good luck and sorry that i have been no help

Answer 14

its cool thanks for trying

Answer 15

Step 1: find the slope of given line.
Step 2: think of relationship between two lines that is if two lines are parallel, the slopes are the same; if two lines are perpendicular then the slope of unknow line is negative reciprocal of given line.
Step 3: use the slope you find in step 2 and the given point, substitute into point-slope form, \[y-y_1=m(x-x_1)\]
step 4: write your equation in standard form (since the given line is in standard form)
