The way I used to think to figure this out is to remember that a slope is "rise over run" or y over x (y/x). You'll want to find the change of y and the change of x. There is a change of -9 between 6 and -3. The change between -2 and 7 is 9 too. 9/-9 equals -1. So the slope is -1.
Answer:
298
Step-by-step explanation:
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
