Question 681394
y = -x + 5
comparing to y = mx + b
m, slope is -1: negative means downward, decreasing line like \
b, y intercept is 5; plot (0, 5)
Starting at (0,5) move down the y axis one and right on the x axis one, repeatedly.
From (0,5) move up on the y axis one and left of the x axis one, repeatedly.

x-2y=-2
2y = x + 2
y = {{{(1/2)x + 2/2}}}
y = {{{(1/2)x + 1}}}
m, slope is {{{1/2}}}: positive slope means upward, increasing line like /
b, y intercept is 1; plot (0,1)
Starting at (0,1) move up the y axis one and right on the x axis 2, repeatedly.
From (0,1) move down the y axis one and left on the x axis 2, repeatedly.
