Question

find the x-intercept and y-intercept of the line?

5x+10y=30 i know

x-intercept=6
and the y-intercept=3

but i need to know how they got it can some one teach me the steps so i can know how to do it myself please

Answer 1

5x + 10y = 30

First you have to change it to Point Slope Form(y = mx + b)

5x + 10y = 30

Subtract 5x to both sides:

10y = -5x + 30

Divide 10 to both sides of the equation:

y = -5/10x + 3

y = -1/2x + 3

So you switched it to Point Slope form.

Point Slope Form:

y = mx + b

Where m = slope

And b = y-intercept

Answer 2

So what's the y-intercept? @ObeyBaby_nemo

Answer 3

Answer 4

Yes, that's correct.

To find the x-intercept input 0 for 'y'.

5x + 10y = 30

5x + 10(0) = 30

5x = 30

Divide 5 to both sides, and you'll get your x-intercept.
