In order to use a graph to write an equation, you first need to have plot points. Pick 2 points on the line if there isn't already any on the graph. After you find two points, find the slope. (Formula: y = mx + b) After you solve the slope, try finding the y-intercept. (Meaning: when x = 0, solve for y) The y-coordinate when you solve it is the value of "b" in the equation. (REMEMBER: y = mx + b) If you have any questions about the formula or the directions, remember to ask! Cheers, mimiisawesome5
