Slope = 20
y-intercept = 60
Step-by-step explanation:
Slope formula is given as![m = \frac{y_2 - y_1}{x_2 - x_1}](/tpl/images/0835/4865/61e71.png)
Pick two points on the line and use their coordinates. Let's pick (1, 80) and (2, 100).
Let,
Plug the values above into the formula for slope:
Slope of the graph is 20.
The y-intercept is the point where the line intercepts the y-axis. Thus, y-intercept = 60.
