Answer (<u>assuming it can be written in slope-intercept form)</u>:
![y = \frac{7}{9} x+\frac{17}{9}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B7%7D%7B9%7D%20x%2B%5Cfrac%7B17%7D%7B9%7D)
Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula,
. Substitute the x and y values of the given points into the formula and solve:
So, the slope is
.
2) Now, use the point-slope formula
to write the equation of the line. Substitute
,
, and
for real values.
Since
represents the slope, substitute
for it. Since
and
represent the x and y values of one point the line intersects, choose from any one of the given points (it doesn't matter which one, either way the result equals the same thing) and substitute its x and y values into the formula as well. (I chose (4,5), as seen below.) From there, isolate y to place the equation in slope-intercept form (
format) and find the following answer:
<span>This is an example of the substitution property of equality, meaning that if pq = 3, you may substitute 3 for pq in another related equation. So if pq+rs=5 is true, then 3+rs=5 is true as well.</span>
Answer:
15 commercials
Step-by-step explanation:
6 commercials --> 24 minute
x commercials --> 60 minute(1 hour)
x*24 = 6*60
clear x
x = (6*60)/24
x= 15
When asking a question you should type english word because some student don't know spanish. If you ask the question like that no one will know.
