You can put this solution on YOUR website! (1.) A line passes through the points (20, 42) and (21, 6).
The slope of the line is m = .
slope=∆y/∆x=(42-6)/(20-21)=36/-1=-36
..
An equation for the line is?
y=-36x+b
solveing for b using one of the coordinates on the line(21,6)
6=-36*21+b
b=762
equation: y=-36x+762
..
(2.) A line has the x-intercept 2 and y-intercept 17.
The slope of the line is m = .
points on the line: (2/0) and (0,17)
slope=(17-0)/(0-2)=-17/2
An equation for the line is: y=-17x/2+17
