x intercept is when y=0:

3x - 5y = 30
3x - 5*0 = 30
3x = 30
x = 10

y intercept is when x=0:

3x - 5y = 30
3*0 - 5y = 30
-5y = 30
y = -6

from 3x-5y=30 for the y-intercepts it uncomplicated ability the place the line cut back the y axis at this y-cost=y-intercept and x=0 considering the fact that there is not any horizontal displacement from 0 3(0)-5y=30 => y= -6. coordinates at this ingredient ;(x,y)=(0,-6) For x-intercept the opposite is real.ie y=0 x-cost=x-intercept 3x-5(0)=30 => x=10 coordinates (10,0)

First rewrite the equation in slope intercept form...

3x - 5y = 30
isolate y.. by doing this is to subtract 3x on both sides
-5y= -3x +30

No get rid of that 5 by dividing it on both sides.. It's more correct make them separate fractions. Like given below

-5y/-5 = -3x/-5 + 30/-5

y= 3x/5 - 6

Make x 0 and the y intercept will be -6..

What you need to do is put a 0 (zero) in place of the x or y... then solve for the remaining variable...


♥3x - 5y = 30 -Replace the x with a zero

3(0) -5y =30

0-5y=30

-5y=30 -Then divide both sides by -5

and you get

y= -6

♥3x - 5y = 30 ---Then replace 0 in for y

3x - 5(0) = 30

3x - 0 = 30

3x = 30 --Divide by 3 to get the x alone

and you get

x=10


Answer: x=10 and y= -6


HOPE THIS HELPS ♥

X intercept is 10, and the Y intercept is -6.

rewrite the problem in slope intercept form

y=-3/5x+6

y intercept is 6
x intercept is 7

th x intercept is when y = 0 so x = 10
the y intercept is when c = 0 so y = 6

x intercept is when y =0

so...
3x+5(0)=30
3x=30
x = 10
x intercept: (10,0)


3(0)+5y=30
5y=30
y=7
y intercept: (0,7)
