Question 299726
7x+5/9y =30 
5y/9=-7x+30
5y=-7x*9+9*30
5y=-63x+270
y=-63x/5+270/5
y=-63x/5+54 
The y intercept=54 
Setting y=0 & solve for x.
0=-63x/5+54
-63x/5=-54
-63x=-54*5
-63x=-270
x=-270/-63
x=4.2857 the x intercept.
Ans.(4.2857,54)
{{{ graph( 300, 200, -6, 5, -10, 60, -63x/5 +54) }}} (graph 300x200 pixels, x from -6 to 5, y from -10 to 60, -63x/5 +54).
