Point slope form slope = 5 passing through (-3,4)

Question

I don't know how to do this at all

Answer 1

... or m = 5, y = 4,  x = -3

 

y = mx + b

 

4 = 5(-3) + b

 

4 = -15 + b

 

Add 15 to both sides, giving b = 19;   Since y = mx + b: y = 5x + 19

Answer 2

point slope form is: (y-y₁) = m(x-x₁) where m is slope and the point they give you is (x₁, y₁)

 

1. First plug in

y - 4 = 5(x - (-3))

 

2. Subtracting a negative makes a positive so fix equation

 

y - 4 = 5(x + 3)

 

3. If you need to put it in slope intercept form:

 

y - 4 = 5(x + 3)  (then distribute the 5 to x + 3)

y - 4 = 5x + 15

y - 4 + 4 = 5x + 15 + 4 (add 4 to both sides to get y by itself)

y = 5x + 19

Answer 3

Graph the line with slope 3  passing through the point (-5, 4)
