m = rise/run = 5 - 65 /500 - 0 =-60/500 =-0.12
The rate of change is -0.12/km. The car uses 0.12 litre of gasoline per km driven. The rate of change is negative since the gasoline is always decreasing.
The slope is unidentified
m=0/4. Slope is zero.
The y-intercept is -2. The slope is 3/4
Equation =y = mx + b y = 2/3x + (-5) The equation of the line is y = 2/3x + (-5)
The y-intercept is -5
m = y2 - y1/x2 - x1 = -1(--5)/ 6-0 = -1+5/ 6 = 4/6 = 2/3 The slope is 2/3
1. Subtract x from both sides and add 4 to both sides. 2. Divide both sides by 2 3. Divide each term on the right side by 2
