Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x - 2 ← is in slope- intercept form
with slope m = -
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = , thus
y = x + c ← is the partial equation of the perpendicular line
To find c substitute (- 12, 7) into the partial equation
7 = - 16 + c ⇒ c = 7 + 16 = 23
y = x + 23 → D

Answer:
75% trabslates to 3/4.
1/4 of 20 students is 5 students.
5 × 3= 15.
75% is 15 students.
So. 4 students prefer social studies and 15 students prefer PE.
