Find two points- pick any number and replace it with x and then solve for y. Write it in the following format: (x, y). Pick another number for x and repeat this process.
Graph these two points: One point that would work in the equation is (4, 0). start at the origin- (0, 0)- and move horizontally by positive four, meaning you move four to the right (if it was negative, you would move four units to the left). Then, because the y-value is zero, you don't move up or down. If you had a positive y-value, the point would go up, and if it was negative, it would go down. Since it is 0, it stays in place. This makes this specific point an x-intercept because it intersects with the x-axis.
You would do the same with the other point and connect them with a ruler, extending out the line and putting arrows at either end of it to signify the it goes on forever.
