9514 1404 393

Answer:

Step-by-step explanation:

Your score total must be 3×75 = 225. Subtracting the two high scores gives ...

225 -95 -79 = 51

The score of 34 is below that value, so it is the one that will be dropped.

You need a test score of 51 on the next test for your average to be 75.

What is the slope of a line that contains the point(-5,4) and has a x intercept of -10?

Naddika [18.5K]

Answer:

$\frac{4}{5}$

Step-by-step explanation:

Based on the information given we can say the two points are (-5, 4) and (-10, 0). An x-intercept is where the line crosses the x-axis giving us a y value of 0.

So, we will use the following formula, where m is equal to the slope.

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Now we will plug in the x and y values given above, (-5, 4) and (-10, 0).

$m=\frac{0-4}{-10+5}\\ m=\frac{-4}{-5}\\ m=\frac{4}{5}$

Note: In the denominator of the first line, the -5 was changed to a 5 because in the original equation, we are told to subtract. When you have two negatives they cancel each other out.
