The total of the scores on the 4 exams must be at least 75 x 4 = 300.
The total scores in the first 3 exams is 68 + 78 + 81 = 227.
Therefore the minimum score needed on the last exam is 300 - 227 = 73.

The answer is a score of at least 73.

What is the equation of the graphed line in point-slope form?
Flura [38]
We first need to find the gradient of the line
\frac{y_{2}- y_{1} } {x_{2}-x_{1} } = \frac{-3-1}{-3-3}= \frac{-4}{-6}= \frac{2}{3}

From the graph, we see the graph intercepts y-axis at -1

Hence, the equation of the line is y= \frac{2}{3}x-1
