Answer:
B. a decrease in their water bill of $3.16.
Step-by-step explanation:
Monthly service charge =$10.10
Volume charge = $1.58 for every 100 cubic feet of water.
Total monthly cost = 1.58x + 10.10
If the Johnson family used less water this month than last month, then they can expect a reduction in their bill by the Volume charge for
.
Volume Charge per of water = $1.58
Therefore: Volume Charge for of water = 2 X $1.58=$3.16
Therefore, the Johnson family can expect a decrease in their water bill of $3.16.
Answer:
Step-by-step explanation:
The slope formula for a straight line is:
Where, 'm' is the slope and 'b' is the y-intercept.
To find the x-intercept of a line, we need to equal 'y' to zero, and then solve for 'x'. In this case we know that the x-intercept is 1, so we have the point (x1, y1)=(1,0). We are given a second point which is: (x0, y0)=(-2, 12).
To find the slope, we use the following formula:
Now, The equation of the line is: y - y0 = m(x-x0). Then, substituting the values of 'm', 'x0' and 'y0' we have that:
The equation of the line using the slope-intercept form is:
