Slope and y-intercept of y equals 2.5x is: Slope is 2.5 and y-intercept is 0
Slope for the equation y equals 7 is zero.
The slope equals 3
Slope = 0
y=x y=1x The slope is one.

if the x equals -1.2 and the y is -4, 4 what is the slope
yes, change in y over change in x equals slope
y is equal to a constant, so the slope is zero.
The slope is 10 and the y intercept is 5
3x + y + z = 63x - y + 2z = 9y + z = 3y + z = 3y = 3 - z (substitute 3 - z for y into the first equation of the system)3x + y + z = 63x + (3 - z) + z = 63x + 3 = 63x = 3x = 1 (substitute 3 - z for y and 1 for x into the second equation of the system)3x - y + 2z = 93(1) - (3 - z) + 2z = 93 - 3 + z + 2z = 93z = 9z = 3 (which yields y = 0)y = 3 - z = 3 - 3 = 0So that solution of the system of the equations is x = 1, y = 0, and z = 3.
