Answer:
$87.50
Step-by-step explanation:
first minus the number of minutes he doesn't have to pay
400 - 150 = 250
then times the number of leftover minutes by how much it costs a minute ($.35 because 35¢ is equal to $.35)
250 × $.35 = $87.50
that's how much.
In order of least to greatest: -5/16 , -3/8 , -0.65 , 2/4
Slope-intercept form is y = mx + b. all you have to do for this question is plug your given information in:
m = -3
b = 7
y = mx + b
y = -3x + 7
Answer:
Step-by-step explanation:
From the given information, we already know two points the line intersects. It states that the line has a y-intercept of 3. The y-intercept is the point at which the line intersects the y-axis. Thus, the line also intersects (0,3). (Remember that all points on the y-axis have an x-value of 0.) Now we have enough information to write an equation.
1) Find the slope of the line with the slope formula, 
. Substitute the x and y values of (-5,2) and (0,3) into the formula and solve:
So, the slope of the line is 
.
2) Now we can write the equation in slope-intercept form, represented by the formula 
. Substitute values for 
and 
in the formula.
The represents the slope, so substitute for it. The represents the y-intercept, so substitute 
for it. This gives the following answer and equation in slope-intercept form:
