There has been a lot of discussion regarding the relationship between Scholastic Aptitude Test (SAT) scores and test-takers’ family income (The New York Times, August 27, 2009). It is generally believed that the wealthier a student’s family, the higher the SAT score. Another commonly used predictor for SAT scores is the student’s grade point average (GPA). Consider the following portion of data collected on 24 students. SAT Income GPA 1,651 47,000 2.79 1,581 34,000 2.97 ⋮ ⋮ ⋮ 1,940 113,000 3.96

i can't read the graph

step-by-step explanation:

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)

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
