find the x and y intercepts for the graph of
y=log%2810-3x%29
the x+ intercept: set y=0
0=log%2810-3x%29... log base 10 is equal to zero for log%281%29=>

1=10-3x ...solve for x
3x=10-1
3x=9
x=9%2F3
x=3 => the x- intercept: at (3,0)
the y- intercept:
now set x=0 and solve for y
y=log%2810-3%2A0%29
y=log%2810%29=>log%2810%2C10%29=1=>
y=1 => the y- intercept: at (0,1)
