First, eliminate the lowest grade (76). Now, find the average/mean of the remaining 4 test grades. To do so, add up all the test grades, then divide them by the total number of test grades:
80+84+91+95=350
350/4=87.5

Step-by-step explanation:
Parallel lines have the same slope.
The slope-intercept form of an equationo f a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
We have the equation of the line in a standard form.
Convert to the slope-intercept form:
<em>subtract 5x from both sides</em>
<em>divide both sides by 2</em>
The slope
Therefore we have:
Substitute the coordinates of the given point (-2, 4):
<em>subtract 5 from both sides</em>
Finally we have:
