Question

What is the equation of the line that has a slope of 3 and goes through the point (-3,-5)?

Answer 1

Answer:

A: y = 3x + 4

Step-by-step explanation:

A slope of 3 is given, so the co-efficient of x must be three

If you are going through point (-3, -5), then you must have a starting point.

Adding 3 to the y coordinate for every x value gives us 4.

This means that the equation must be adding 4 to x.

So, the answer is y = 3x + 4, or A.

Answer 2

Answer:

y = 3x -4

Step-by-step explanation:

point slope form:

y - y1 = m(x-x1)

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

y+5 = 3x + 9

y = 3x -4
