Question

1. The linear equation y = 3x tells us that this line is going to be more vertical or horizontal? Explain.

Answer 1

More vertical. 
y=x, where the slope is 1, is a line that forms a 45 degree angle with the positive part of the x axis. y=3x has a bigger slope, so it is going to rise 3 times faster than y=x so the line is more vertical
I hope that makes sense.

Answer 2

The linear equation y=3x tells you that it’s going more vertical
