Answer:

The equation of the line is y=1.4x+6.8

Step-by-step explanation:

Given 2 points on the graph, you can find the slope using the equation: m=\frac{y2-x2}{y1-x1} . The 2 points are (-7, -3) and (-2, 4). X1 is -7, X2 is -2, Y1 is -3, Y2 is 4. The slope would be 1.4 once you plug in the numbers to the equation to finding the slope. Once you find the slope, use one of the points to find the y-intercept along with the slope you found and the y-intercept will be 6.8.
