📌 Slope-Intercept Form ➜ the slope-intercept form of an equation of a line with slope 𝑚 and 𝑦-intercept (0, 𝑏) is 𝑦 = 𝑚𝑥 + 𝑏
📌 𝑦-intercept ➜ the point where the line crosses the 𝑦-axis. It has the form (0, 𝑏).
📌 In mathematics, the ‘tilt’ of a line is called the SLOPE of the line.
📌 Slope of Line ➜ 𝑚 = (rise)/(run).
Between two points on the line, the rise measures the vertical change, and the run measures the horizontal change.
📌 Slope Formula ➜ the slope of the line between two points (𝑥1, 𝑦1) and (𝑥2, 𝑦2) is 𝑚 = (𝑦2 - 𝑦1)/(𝑥2 - 𝑥1)
📌 How to Find an Equation of a Line Given Two Points
✓ Step 1. Find the slope using the given points.
✓ Step 2. Choose one point.
✓ Step 3. Substitute the values into the Slope-Intercept Form.
✓ Step 4. Write the equation in slope-intercept form.
