How to Write a Linear Inequality from a Graph?
Step 1: Identify the slope and (y)-intercept of the line Step 2: Determine whether the line is solid or dashed Step 3: Determine whether the inequality is “greater than” or “less than Step 4: Write the inequality using (“y”) for the (y)-coordinate and (“x”) for the (x)-coordinate Step 5: Write the final inequality Writing a […]
How to Write a Point-slope Form Equation from a Graph?
TL;DR: Writing a line’s equation in point-slope form straight from a graph is a three-step routine you can run on autopilot. Pick any clear point on the line (call it x1, y1). Use two more clear points to compute the slope m. Plug everything into y minus y1 equals m times (x minus x1). The […]
