Select the correct answer. What is the equation of the line that has a slope of 3 and goes through the point (-3,-5)?
O A. y = 3x + 4
OB. y= 3x - 14
O C. y= 3x - 4
OD. y = 3x + 12

A

Step-by-step explanation:

Put your information in the the point slope formula y-y1=m(x-x1)

This will give you y+5=3(x+3)

simplify

y+5=3x+9

Now subtract 5

y=3x+4

34

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
