Maybe one where the y is actually changing. So I'd like to pick the two points that make things a little bit simpler. So I'll pick the point 4, 2 and 7, 0. So our change in x here, if we go from 4 to 7, our change in x is equal to 3.
We can work it out.
Notice from this equation that the slope represents the change in y-value per unit of change in the x-value. That's one thing that's going to help you, and another thing that's going to be helpful for you is if you can look for the change in the table.
So when x is equal to sorry, when x is equal to y is equal to 0. Determine the Point Where the Line Crosses the Vertical Axis After solving for the slope, the next unknown to solve for is the term b, which is the y-intercept.
But they don't give us any of those.
