Stop guessing and start solving. In this video, we break down the two most powerful ways to find the equation of a line: the Slope-Intercept Form (y = mx + c) and the Point-Slope Form (y - y1= m(x - x1)).
We don't just memorize the formulas; we apply them to three common exam scenarios to see which method works best.
We cover:
• Method 1: Using y = mx + c to solve for c.
• Method 2: Plugging directly into y - y1= m(x - x1).
• Scenario A: When you are given a Gradient & a Random Point.
• Scenario B: When you are given a Gradient & Y-Intercept
• Scenario C: When you are given a Gradient & X-Intercept
Practice Problems (Try using both methods!):
1. Find the equation of a line with Gradient m = 4 passing through (1, 3).
2. Find the equation of a line with Gradient m = -1 and y-intercept 5.
3. Find the equation of a line with Gradient m = 2 and x-intercept 3.
