Step-by-step explanation:
Use the slope-intercept form:
m is the slope and b is the y-intercept. Looking at the graph, you can find the y-intercept. The y-intercept is the point where x equals 0:
To find the slope, take any two points from the line:
Use the slope formula for when you have two points:
The rise over run is the change in the y-axis over the change of the x-axis. Insert the appropriate values:
Simplify parentheses (two negatives makes a positive):
Simplify (two negatives make a positive):
The slope is and the y-intercept is
. Insert these into the equation:
Finito.
Answer:
A
Step-by-step explanation:
The pattern in the table adds 1.50 for ever 15 minutes. That means per minute it adds or 10 cents. This means you multiply each minute by 0.10 to find the cost. This is the equation c = 0.10m.
