Question

rewrite the equation in slope-intercept form.

Answer 1

start at the beginning, and finish when done

Answer 2

What is the equation?

Answer 3

I don't know how to start it

Answer 4

the equation is 4x + 5y = 15

Answer 5

OKay so slope intercept form is Y=mx+b. The letter B is the Y intercept, this means the point in the graph where the line goes through Y. Got it so far?

Answer 6

OK so you want to get Y by itself

Answer 7

So if you want Y on one side of the equation by itself what do you do?

Answer 8

yeap, solve \(\bf 4x + 5{\color{brown}{ y}} = 15\) for "y"

see what you get

Answer 9

@jdoe0001 You got it from here?

Answer 10

well.. is too simple methinks, but I can keep an eye

Answer 11

do I subtract 4x from the left side?

Answer 12

so I did that and got:

5y = 15 -4x


I think I'm suppose to divide 5 from all of the numbers & got:

y = 3 -4/5x
or y = 4/5x + 3 ????

Answer 13

well
yes, divide by 5
thus \(\bf 4x + 5y = 15\implies 5y=15-4x\implies y=\cfrac{-4x+15}{5}
\\ \quad \\
y=\cfrac{-4}{5}x+\cfrac{\cancel{15}}{\cancel{5}}\implies y=-\cfrac{4}{5}x+3\impliedby \textit{slope-intercept form}\)

you'd put the "x" part first on the right-hand-side
