Mrs. Shaughnessy’s science class and Mr. Ruth’s social studies class are going on two separate field trips. They have the same budget for their trips. Mrs. Shaughnessy’s class has 30 students, and they are taking a bus to a planetarium. Mr. Ruth’s class of 20 students is taking the subway to a museum. Admission to the planetarium is 12 the cost of admission to the museum, as shown in the table. What is the cost of admission per student to the museum?

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
