Answer:
y = -5x + 8
Explanation:
To find the equation of a graphed line, find the y-intercept and the slope in order to write the equation in y-intercept (y=mx+b) form. Slope is the change in y over the change in x. Find two points on the line and draw a slope triangle connecting the two points. Label the legs of the triangle. This will tell you the rise (change in y, numerator) value and the run (change in x, denominator) value. The y-intercept comes from the point where the line passes the y-axis. The y-value of the coordinate is the y-intercept, or the "b" value. Plug in the slope, m, and the y-intercept, b, to the slope-intercept form of the line.
In this case the line crosses the y axis at positive 8 and the slope is -5.
