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. And so I get 1 is equal to 3 plus b. I can subtract 3 from both sides, and I get negative 2 is equal to b. So the equation of the line is going to be y is equal to 6x minus 2. That is the equation of the tangent line.
