1. What is the slope of a line that is parallel to the line represented by the equation 3x + 4y = 12?
inn [45]

Answer:

Explained Below

Step-by-step explanation:

first we need to turn the equation into point slope form.

3x + 4y = 12

4y = -3x + 12

y = -0.75 + 3

Parallel lines don't have a change in slope because they run parallel. Your answer would be -0.75 or -3/4.
