So the general equation for this line is y is equal to mx plus b. This is the slope, this is the y-intercept. We already know that the slope is 6. And then we can use the fact that the line goes through the point 1 half 1 to figure out what b is. So when y is 1, 1 is equal to our slope times x. x is 1 half. Or another way to say it, when x is 1 half, y is 1, plus some y-intercept. So if I take x as 1 half, I multiply it times the slope, plus the y-intercept, I should get 1.
