What is the equation of the line that is parallel to the line defined by the equation y = 3x + 6 and goes through the point (3,
saw5 [17]

Answer:

Step-by-step explanation:

Parallel lines have the same slope. The slope of the given line is 3. The easy way to do this, the one that uses our logical brains as opposed to our mathematical brain, tells us that since there is only one choice that has a given slope of 3, that is the one that we want. The second choice down is the only one that has a slope of 3.

Mathematically,

y-2=3(x-3) and

y-2=3x=9 and

y=3x-9+2 so

y = 3x - 7 (the second choice)
