Answer:
Step-by-step explanation:
If it's parallel, that means it has the same slope: -1/5.
Use point-slope form to write the equation:
y - 4 = -1/5 (x - 7)
If you wish to write in point-intercept form:
y - 4 = -1/5 x + 7/5
y = -1/5 x + 27/5
If two lines are parallel, it means that they will have the same gradient:
And remember, the equation of a line is y = mx +c
-----------------------------------
So we know that the equation of the parallel line is:
y = - x + c through point (7, 4)
All we need to do now is to work out what c is
Note: at point (7,4) x = 7 , and y = 4.
So to work out c, we substitute in the values of x and y, and solve:
y = - x + c
4 = - * 7 + c
4 = -1.4 + c
5.4 = c
----------------------------------
Finally, we just put the value of c back into the original equation
y = - x + 5.4
------------------------------------------
Answer:
The equation of the a line parallel to y = - x + 3 through point (7,4)
is: y = - x + 5.4

Answer:
21) $90 22) $144 23) $240.5
Step-by-step explanation:
21) Cost to Store(CTS): 75 Markup(M): 20
Turn 20% into 0.20
Multiply the CTS, 75, by 0.20 to get 15
Add 15 and 75 together to get 90
22) CTS: 90 M:60
Turn 60% into 0.60
Multiply the CTS, 90, to 0.60 to get 54
Add 54 and 90 together to get 144
23) CTS: 130 M:85
Turn 85 into 0.85
Multiply the CTS, 130, to 0.85 to get 110.5
Add 110.5 and 130 together to get 240.5
