Step #1: Find the slope.
Slope is "rise over run" and see the attached graph to see
the rise = 1
the run = 4
and this gives a slope of 1/4.
Step 2: Find the y-intercept.
The y-intercept is where this graph hits the vertical axis. That happens at a height of 20, so your y-intercept is (0,20) and your b-value for the slope-intercept form is 20.
Step 3: Put it all together:
y = mx + b becomes
Answer:
Pat a) The unit rate of graph at left is
Part b) The unit rate of graph at right is
see the attached figure
Step-by-step explanation:
we know that
The unit rate of a linear equation is the same that the slope of the linear equation
step 1
Find the slope of the graph at left
This graph represent a proportional relationship (because the line passes through the origin)
The slope is equal to the constant of proportionality k
we have the point (1,25)
substitute the values in the formula
step 2
Find the slope of the graph at right
we have the points (2,80) and (3,120)
This graph represent a proportional relationship (because the line passes through the origin)
The slope is equal to the constant of proportionality k
Is necessary only one point to determine the constant of proportionality
take the point (2,80)
substitute the values
<u>Verify</u>
The formula to calculate the slope between two points is equal to
we have the points (2,80) and (3,120)
substitute the values
Answer:
$13,795
Step-by-step explanation:
15500/x=100/11
(15500/x)*x=(100/11)*x - we multiply both sides of the equation by x
15500=9.0909090909091*x - we divide both sides of the equation by (9.0909090909091) to get x
15500/9.0909090909091=x
1705=x
x=1705
now we have:
11% of 15500=1705
0.88x distributive property and isolate the variables
