Mathematics
1 answer:
Alexandra [31]3 years ago
7 0

Answer:

The slope is 7/7 or 1.

Step-by-step explanation:

Find any two points on the line. I chose (0,7) and (-7,0).

Put rise over run.

7-0

———

0 – -7

this would equal 7/7 which simplifies to 1.

Hope this helped!

Vanyuwa [196]
Price, when purchased online:  1.30($160)
Price, when purchased at superstore:  1.40($160)

Difference in prices:  1.40($160) - 1.30($160) = 0.10($160) = $16

A higher markup brings a higher retail price.

What is the equation of the line with a slope of 3/4 that goes through the point (4, 1) in slope-intercept form?
Svetach [21]

Answer:

y=\frac{3}{4}x+-2

Step-by-step explanation:

We do not have enough information for slope intercept form. But we can use the point-slope formula to find the information. The formula is y -y_{1} =m(x -x_{1}) where we substitute a point (x,y) for (x_{1},y_{1}).  

We have m=3/4 and (4, 1). We input m and x_{1} =4\\y_{1}=1.

y-1=\frac{3}{4} (x-4)

We now simplify the parenthesis and solve for y.

y-1=\frac{3}{4} (x-4)\\y-1=\frac{3}{4}x+\frac{3}{4} (-4)

We convert -4 into a fraction with 1 as the denominator.

y-1=\frac{3}{4}x+\frac{3}{4} (\frac{-4}{1} )\\y-1=\frac{3}{4}x+\frac{-12}{4}\\y-1=\frac{3}{4}x+-3

We add 1 to both sides to isolate y,

y-1+1=\frac{3}{4}x+-3+1\\y=\frac{3}{4}x+-2

This is slope intercept form. The line as slope 3/4 and y-intercept (0,2) or b=2.
