The slope is -4
There is no "equals" sign therefore "x-9" is NOT an equation.
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 )
y - 3x = 8 standard form is y = mx + b m = slope y = 3x + 8 in this form slope m is 3 The perpendicular line slope is the negative inverse of m -1/m = -1/3
y = x
There is no y-intercept or slope for this given equation, because its graph is a vertical line perpendicular to the x-axis.
the slope will be positive 1.5x the whole equation is y=4.5+1.5x
It is: 1/5
It is: -1/2
