[Easy]x-y intercepts[EASY]

[Picnore]

Hey guys

How would I find the x and y intercepts for this:

-5x + 2y = 10

It SHOULD end up like
y = (number)x +/- (number)

Add 5 to both sides so itll be -


2y = 5x + 10

Divide by 2 so itll be

y = 5/2x + 5

Y = mx+b
So you have to change it to that form by adding 5x to both sides (Multiplication prop. of equality I believe).

2y = 5x + 10
Then divide both sides by two to get rid of the two on the left side (So you are left with only Y)

Y = 5/2x + 5

Y-intercept: 5
X-intercept: -2

EDIT: From the equation in slope-intercept form above, the y-intercept is just the "b" part of the mx+b equation. To find the x-intercept, set y equal to 0 and solve for x.

These values can be found w/o getting the equation into the mx+b form

algebra its easy

Alright, got it. Thanks for the help guys!
