Step-by-step explanation:
The linear equation for that represents the above data is given in slope-intercept form as
, where:
m = slope =![\frac{y_2 - y_1}{x_2 - x_1}](/tpl/images/0943/4503/204ff.png)
b = starting value = y-intercept = 2,400
Slope of the linear equation using (0, 2400) and (10, 4000):
Substitute m = 160, and b = 2,400 in
.
Thus, the linear equation in slope-intercept form would be:
✅![y = 160x + 2400](/tpl/images/0943/4503/3f5af.png)
