Answer:
Slope for the first would be 3 and the y intercept is 1. For the second the slope is -4 and the y intercept is 140.
Explanation:
For the first one the difference between the first second point is up 6 and over 2 so 6/2= 3 or slope and the y intercept is just where the line intersects the y axis.
For the second question the difference between the points is down 20 units and over 5 so -20/5= slope of -4, and the line intersects the y axis at 140 so that is the y intercept.
If the x value is zero then the y value is the y intercept.
