Answer:
1) 0.5
2)-2
3)-23
Step-by-step explanation:
1) -3×1=-3
-3+2.5= 0.5
2) -3×1.5=-4.5
-4.5+2.5= -2
3) -3×8.5=-25.5
-25.5+2.5=-23

Answer:

Step-by-step explanation:
step 1
Find the slope of the line that is perpendicular to the given line
we have
-----> given line
The slope of the given line is

Remember that
If two lines are perpendicular, then their slopes are opposite reciprocal
therefore
The slope of the line that is perpendicular to the given line is

step 2
Find the equation of the line in slope intercept form

we have

substitute

solve for b

therefore

In this case the areas would be exactly the same. To prove this, think of a can of stain as 4 inches wide by 6 inches tall/long. If the can of paint is 8 inches wide and 3 inches tall/ long, both areas would be 24 inches squared. By cutting one dimension in half and doubling the other dimension, you do not change the overall area.
