Step-by-step explanation:
25 questions, 2 points each.
that means there were 25×2 = 50 points in total.
Gideon got 42 out of the 50.
100% = 50
1% = 100%/100 = 50/100 = 0.5
42 is how many % ? as many as 1% (0.5) fits into 42.
so,
42/0.5 = 42×2 = 84%
he scored 84%.
Answer:

Step-by-step explanation:
First, find the <em>rate of change</em> [<em>slope</em>]:

Then, plug the coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope Formula</em> because since you get it done much faster that way. It does not matter which ordered pair you choose:
15 = 2[3] + b
6

_______________________________________________
5 = 2[−2] + b
−4

** You see? I told you it did not matter which ordered pair you choose because you will always get the exact same result.
