(92+73+87+91)/4=x
92+73+87+91=343
343/4=86%
The average of the student’s grade is 86%
So, for the slope, you’ll have to do rise over run (or change in y over change in x) so it’ll be 2/1 so your slope will be 2
And the y intercept can be found if you compare the equation give to y=mx+b, this is because b is the y-intercept value which is those equation will be 2.

<u>Answer:</u>
x = -7
<u>Step-by-step explanation:</u>
<em>f(x) </em>= -x - 1
when <em>f(x) </em>= 6:
- x - 1 = 6
-x = 7 [Add 1 to both sides]
x = -7 [Divide both sides by -1]
Answer: The reason you cross multiply fractions is to compare them. Cross multiplying fractions tells us if the two fractions are equal or which one is greater. This is especially useful when you are working with larger fractions that you aren't sure how to reduce.
It works cause they have the same denominator
bruh
