4/9x-y=4 find the y intercept and x intercept. a: ( , ) b: ( , ) than plot. i just need to know how to find it.

Convert the equation to  slope intercept form ) y = mx + b):-

-y = -4/9x + 4
y = 4/9x - 4

the y intercept is where y = -4 =  at the point (0,-4)

To find x intercept put y = 0 and solve:-
0 = 4.9x - 4

 4.9x = 4
x = 4/4.9  = 0.82

x intercept is at (0.82,0) 

The y intercept is 4 and the x intercept is 0
