Answer:
Step-by-step explanation:
An equation in standard form is:
Solving (a):
Given
--- slope
--- y intercept
Required: Determine the equation
An equation has the form:
Substitute values for m and b
Multiply through by 5
Add 3x to both sides
Solving (b):
Given
--- slope
--- y intercept
Required: Determine the equation
An equation has the form:
Substitute values for m and b
Multiply through by 3
Subtract 2x from both sides
Answer:
(15,0) , (0,6)
Step-by-step explanation:
Same concept as the previous 2 questions.
x-intercept is where the line touches the x-axis, and y = 0.
when y = 0,
12x + 30(0) = 180
12x = 180
x =
x = 15
Therefore the coordinates of the x-intercept is (15,0)
y-intercept is where the line touches the y-axis, and x = 0.
when x = 0,
12(0) + 30y = 180
30y = 180
y =
y = 6
Therefore the coordinates of the y-intercept is (0,6)

Answer:
Step-by-step explanation:
To estimate the total cost, I would say that it is roughly $2 per gallon, and she is buying roughly 9 gallons, so the total cost ≈ 2 x 9 = $18.
