Question

Find the x-intercept for the graph of the following equation.
18x + 12y = 72

Answer 1

make y=0 (substitute 0 into y) and solve for x.

then if you need to write it in coordinate form

Answer 2

so 18x+y=72

Answer 3

no substitute 0 in for y\[18x+12(0)=72\]\[18x=72\]\[x=\frac{ 72 }{ 18 }\]
