The equation for the line is y = mx +b
the slope is the value of m
For example if y = 3x +4 the that is the equation that completely defines the line; its slope is 3
For the line 2x + y = 8 , the slope equals ( -2 ) so the required slope of the line which is perpendicular to it is equal to (+1/2 )
The equation has no slope. The graph of the equation is a straight line with a slope of -1 .
Which of the following is the point-slope equation of the line with a slope equals -4 and a point of -2 3?
Slope = 4
The slope is ' 1 '. As you move along the line, any change in 'x' produces an equal change in 'y'.

what is the slope of the line that has the equation 4x+2y=12?
The slope of the graph of that equation is -1.
Slope = 3
the slope is 0
The equation for the slope of a line is y=mx+b
