x = 25/3 = 8 1/3 " and "y = 25/(-9) = -2 7/9x=253=813 and y=259=279

Explanation:

To find the x-intercept, make y = 0.
3x -9(0) = 253x9(0)=25

x = 25/3 = 8 1/3x=253=813

To find the y-intercept, make x = 0.

3(0) -9y = 253(0)9y=25

y = 25/(-9) = -2 7/9y=259=279

For the y intercept you can also change the equation into standard form , y = mx + cy=mx+c

3x -9y = 253x9y=25

3x- 25 = 9y3x25=9y

y = 1/3x -25/9 " " c = -25/9 y=13x259 c=259
