the x intercept is where the line crosses the x axis or where y=0 the y intercept is where the line crosses the y axis or where x=0
xintercept set y=0 and solve for x 0=-12x+4 add 12x both sides 12x=4 divide by 12 x=1/3 the x intercept is 1/3 not listed so I assume it is y=-1/2x+4, which yeilds x=-2
x intercept using y=-1/2x+4 set x=0 y=-1/2(0)+4 y=0+4 y=4 y intercept is 4
assumign you forgot the slash to make the fraction to make y=-1/2x+4
