Question 6 • CMS 2026-2027 NC Math 1 CREDIT RECOVERY
What is the equation, in slope-intercept form, of the line that is perpendicular to the line y minus 4 is equal to negative 2 thirds times open paren x minus 6 close paren and passes through the point open paren negative 2 comma negative 2 close paren ?
Answer
A
y is equal to negative 2 thirds x plus 10 thirds
B
y is equal to negative 2 thirds x minus 10 thirds
C
y is equal to 3 halves x plus 1
D
y is equal to 3 halves x minus 1
Explanation
The given line has slope −2/3, so a perpendicular line has slope 3/2, the negative reciprocal. Using the point (−2, −2) in y = (3/2)x + b gives −2 = (3/2)(−2) + b, so b = 1. The equation is y = (3/2)x + 1, which is choice D.
