Answer:
Marilee wants to earn an "A" in a class and needs an overall average of at least Her test grades are 88 , 92,100 , and 80 . The average of her quizzes is 90 and counts as one test grade. The final exam counts as 2.5 test grades. What scores on the final exam would result in Marilee's overall average of 92 or greater? (See Example 9
To solve this you have to add 98 and 82 together then divide by three so the answer would be 60
The given equation is,

It can be rewritten in the form of y=mx+c, where c is the y intercept.
Hence,

Put different values for x and find value of y.
When x=0, y=1.
When x=1,

The graph is,
1.6+x-3.2=-2+5.6
simplify
-1.6+x=3.6
+1.6 both sides
x=5.2
Answer:5.9 x10-5
