That's a horizontal line, with a slope of zero.
(You can't see it on the graph, because it lays right on top of the x-axis,
and you can't tell that it's there.)
Slope and y-intercept of y equals 2.5x is: Slope is 2.5 and y-intercept is 0
Slope=3, y-intercept=0. y=3x or y=3x+0

y = x + 0
Slope and y-intercept of y equals 2.5x is: Slope is 2.5 and y-intercept is 0
Slope = 0

Zero. Y=4 is a horizontal line.
y = x + 0
0.
the slope is 0

It is in slope intercept form. The slope is 0 and the y-intercept is -2.
The slope equation is y = mx + b where m is slope for y = 3 we have y = 0 (x) +3 so m = 0 = slope So slope is zero line is constant y = 3
