Slope intercept form is y=mx+b. So let's use the given equation and turn it into this form.
Move the -3x to the right side
Divide both sides by -5
This should be your answer, let me know if you need any clarifications, thanks!
The greatest common factor of the three numbers is 15
The correct equation of the line is Y=-2x-1 :)
The answer is $89.28.
Let's use the proportion for this:
If 1400 ft² costs $125,000, 1 ft² will cost x:
1400 ft² : $125,000 = 1 ft² : x
Now, crossing the products:
x · 1400 ft² = $125,000 · 1 ft²
x <span>· 1400 = $125,000
x = $125,000 </span>÷ 1400
x = $89.28
Therefore, 1 square foot costs $89.28.
Note that you get 2.5 from 9 by subtracting 6.5. You get -4 from 2.5 by subtracting 6.5. Thus, the common diff. is -6.5.
