The slope formula is the changes of two y-values over/to the changes of two x-values.

Substitute two given points in the formula to find the slope. The m-term represents the slope from y = mx+b.

Answer
Hope this helps and let me know if you have any doubts!
A. 5
B. -3/1
C. Negative
D. You have to go down 3 over to the right one from where your y-intercept is.
To plot the y intercept plot (0,5)
To plot the next point go down 3 over 1 to the right from the y-ing
Use this equation to solve the problem:
x - (x * .25) = 40
This equation is saying the original price times itself by 25% is 40.
x - (x * .25) = 40
Simplify.
x - .25x = 40
.75x = 40
Divide both sides by .75.
x = 53.33
The original price was $53.33
Answer:

Step-by-step explanation:
Given equation:

Solving for unknown variable 
Adding 8 both sides by additive property of equality.


Squaring both sides to remove the square root.


Adding 5 both sides by additive property of equality.


Dividing both sides by 6 to isolate 

∴

x=8→h(8)=2(8)^2+5(8)+2=2(64)+40+2=128+40+2→h(8)=170
x=8→f(8)=3^8+2=6,561+2→f(8)=5,563>170=h(8)
3) Yes
4) No
5) Yes
rg=[g(3)-g(2)]/(3-2)=[g(3)-g(2)]/1→rg=g(3)-g(2)
g(3)=20(3)+4=60+4→g(3)=64
g(2)=20(2)+4=40+4→g(2)=44
rg=64-44→rg=20
rf=f(3)-f(2)
f(3)=3^3+2=27+2→f(3)=29
f(2)=3^2+2=9+2→f(2)=11
rf=29-11→rf=18
rh=h(3)-h(2)
h(3)=2(3)^2+5(3)+2=2(9)+15+2=18+15+2→h(3)=35
h(2)=2(2)^2+5(2)+2=2(4)+10+2=8+10+2→h(2)=20
rh=35-20→rh=15
rg=20>18=rf
rg=20>15=rh
6) No
x=4→g(4)=20(4)+4=80+4→g(4)=84
x=4→h(4)=2(4)^2+5(4)+2=2(16)+20+2=32+20+2→h(4)=54
x=4→f(4)=3^4+2=81+2→f(4)=83>54=h(4)
f(4)=83<84=g(4)
