Slope is like a hill's steepness. We find it by dividing the vertical change (rise) by the horizontal change (run). If we move right on a graph and go up, the slope is positive. If we go down, it's negative. We can find the slope between any two points on a line, and it's always the same.
Δ x = x − x 0. So, we can subtract. x 0. from both sides of the second kinematic equation shown above and write it as: Δ x = v x 0 t + 1 2 a x t 2. v x 2 = v x 0 2 + 2 a x Δ x. Δ x t = v 0 + v 2. These are the same equations as above, just written with different notation.

Discover how the derivative of a function reveals the slope of the tangent line at any point on the graph. We'll explore how to use this powerful tool to determine the equation of the tangent line, enhancing our understanding of instantaneous rates of change.
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept). We can rewrite an equation in point-slope form to be in slope-intercept form y=mx+b, to highlight the same line's slope and y-intercept.
Learn how to graph lines whose equations are given in the slope-intercept form y=mx+b.
