See the entire solution process below:

Explanation:

To find the y-intercept, set x = 0x=0 and solve for yy:

-5x + 6y = 305x+6y=30 becomes:

(-5 xx 0) + 6y = 30(5×0)+6y=30

0 + 6y = 300+6y=30

6y = 306y=30

(6y)/color(red)(6) = 30/color(red)(6)6y6=306

(color(red)(cancel(color(black)(6)))y)/cancel(color(red)(6)) = 5

y = 5

The y-intercept is y = 5 or (0, 5)

To find the x-intercept, set y = 0 and solve for x:

-5x + 6y = 30 becomes:

-5x + (6 xx 0) = 30

-5x + 0 = 30

-5x = 30

(-5x)/color(red)(-5) = 30/color(red)(-5)

(color(red)(cancel(color(black)(-5)))x)/cancel(color(red)(-5)) = -6

x = -6

The x-intercept is x = -6 or (-6, 0)
