Question

What is the equation of this graphed line ?

Answer 1

Equations of straight lines are in the form y = mx + c (m and c are numbers). m is the gradient of the line and c is the y-intercept (where the graph crosses the y-axis).

Answer 2

Use the slope formula to calculate the slope: y2-y1/x2-x1. After that, you can use y = mx + b to find the y intercept’s value.
