Step-by-step explanation:
in y=mx+b the number next to x is always the m/slope and the number without a variable is always the b.
Answer:
The least number of questions a student can answer correctly is 32
Step-by-step explanation:
Let
x -----> the number of questions answered correctly
y ----> the total number of questions on a test

we know that
For a student to earn and A or B on a test, the ratio must be greater than or equal to 0.8
so

For y=40 questions
Find the value of x
substitute

solve for x
Multiply both sides by 40


so
The least number of questions a student can answer correctly is 32
<u><em>Verify the ratio</em></u>
For x=32, y=40

Compare
----> is ok
