Question

I don't get this at all

Answer 1

Type of slope is if it is negative or positive so looking from left to right does the line go down or up. For 1 it is positive but for 3 it is a negative slope. And triangle y(delta y)/ delta x is basically y2-y1/x2-x1. So pick two point and plug In the numbers. So slope of number one is 1/2 ( you could also count the rise over run from one point to another too)

Answer 2

ok you take the first point at the bottem and you count up and then across

rember the line that  point a is on its it negitive so the point is at -3,-4 so count up from that and ten count the spaces you go to the left to get to point B.
