Slopeintercept form looks like this: y=mx+b m is the slope, and b is the yintercept. Your equation is y=4x8. Any time there is a minus sign before m, the slope is negative; any time there is a minus sign before b, the yintercept is negative. In your equation, the slope is positive and the yintercept is negative. I'm sure you can figure out on your own what those are, since your equation is already in slopeintercept form. The xintercept is when the line crosses the xaxis. Whenever a point is on the xaxis, its ycoordinate is zero. So, to find the xintercept, you simply have to make y in your equation zero and solve for x: Write your equation: y=4x8 Substitute 0 for y: 0=4x8 Add 8 to both sides: 8=4x Divide both sides by 4: 2=x Now you know that at the xintercept, x=2. However, x=2 is not the xintercept, it is a line. The xintercept is a point, and must be written (2,0). The same goes for the yintercept: don't forget to write it as a point.
