The equation is y = mx + b, where m is the slope, and b is the y-intercept. Our equation is y = -3x - 5, but it is minus, not plus, and this is because our y-intercept is negative. So, knowing this, we can determine that our y-intercept is -5.
he slope intercept form is probably the most frequently used way to express equation of a line. To be able to use slope intercept form, all that you need to be able to do is 1) find theslope of a line and 2) find the y-intercept of a lin
