Question 8 • Mathematics 8

A line passes through the point open paren 4 comma negative 6 close paren and has a slope of negative 3 fourths Which is the equation of the line?

Answer
A
y is equal to negative 3 x minus 3 fourths
B
y is equal to negative 3 fourths x minus 6
C
y is equal to negative 3 fourths x minus 3
D
y is equal to negative 6 x minus 3 fourths

Explanation

Use the slope-intercept form y = mx + b, where the slope m is −3/4. Substitute the point (4, −6): −6 = (−3/4)(4) + b = −3 + b, so b = −3. The equation is y = −3/4x − 3, which is choice C.
