Which equation represents the number of points in the problem below? A test is worth 60 points. Multiple-choice questions are worth 2 points, and
short-answer questions are worth 5 points. If the test has 15 questions, how
many multiple-choice questions are there?

B

Step-by-step explanation:

You could solve this and verify with a system of equations, but b is correct! :) have a good day!

2m+5s=60

Step-by-step explanation:

2m+5s=60

Since each multiple choice is 2 points, we have 2m and since every short answer is 5 points we have 5s. The total number of points is 60 so we have that equal to 60.

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3
