What is the relationship between the lines determined by the following two equations? 15x−3y=−12 y = 5x + 7 answers a parallel , b they are the same line, c perpendicular, d neither parallel nor perpendicular

A

Step-by-step explanation:

2nd equation is given as:

y = 5x + 7

Let's put first equation in this form:

The equation of a line is given as:

y = mx + b

Where m is the slope

So for first line:

Slope = 5

For 2nd line:

Slope = 5

As we can see, the slopes are equal, thus the lines are parallel

Answer choice A is right

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)
