What is the equation of the line passing through the point (-4, -5) and having a slope of 4?
a. y= 4x + 21
b. y= 4x - 21
c. y= 4x + 11
d. y= 4x - 11

C

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 )

here m = 4, thus

y = 4x + c ← is the partial equation

To find c substitute (- 4, - 5) into the partial equation

- 5 = - 16 + c ⇒ c = - 5 + 16 = 11

y = 4x + 11 → C

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!
