Use Linear Equations in Slope Intercept Form

Given a Slope and Coordinate

• Define the variables we know– m, (x, y)

• Substitute into slope intercept form– y = mx +b

• Solve for y intercept (b)• Re-write equation in Slope Intercept Form

using Slope(m) & y-intercept(b)

Given Two Coordinates

• Find the Slope (m)!• Pick one coordinate, define the variables we

know, m, (x, y)• Substitute into slope intercept form

y = mx +b• Solve for y intercept (b)• Re-write equation in Slope Intercept Form

using Slope(m) & y-intercept(b)
