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)
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.
