Question 2 • Mathematics 8

A line has a slope of negative 2 thirds and passes through the point open paren negative 3 comma 8 close paren What is the equation of the line?

Answer
A
y is equal to 8 x minus 2 thirds
B
y is equal to 6 x minus 2 thirds
C
y is equal to negative 2 thirds x plus 6
D
y is equal to negative 2 thirds x plus 8

Explanation

Use the slope-intercept form y = mx + b, where m = -2/3. Substitute the point (-3, 8): 8 = (-2/3)(-3) + b = 2 + b, so b = 6. Therefore, the equation is y = -(2/3)x + 6, which is choice C.
