To find the slope of the line:
(y2-y1)/(x2-x1)
(14-5)/(4-1)=(9)/(3)=3
Only one of your 4 possible answers has 3 as a slope. However, plugging in each point into the y=mx+b equation, the y-intercept consistently comes out as 2..
y=mx+b
14=3(4)+b b=2
5=3(1)+b b=2
y=3x+2
If there is a consistent, positive slope (from your question, this does not seem to have a quadratic as an option), 3x+5 is not even a viable solution because x=1 when the y-value is 5 (and thus no other x value {0} could have a y-value of 5). It seems as though you have a typo on your hands. Hopefully this helps?
297 is the sum of F and 211
297 = f+211
Answer:
C is correct
Step-by-step explanation:
Comparing the to equation with slope intercept form: 
The second equation has the greatest slope, which is indicating that the line is steeper.
Answer:
2x+8 and 2(4+x)
Step-by-step explanation:
Its 2x+8 because all you have to do is distribute the 2. So 2 times x is 2x and 2 times 4 is 8. You can just rearrange it for 2(4+x)
I think it is the third and the fourth
