Answer:
17
Step-by-step explanation:
f(x) = x + 8
f(9) = 9 + 8
= 17
The standard form of any linear equation with two variables is

, where a, b, and c are constants. To convert this equation to standard form, simply subtract

from both sides to get

We could leave it in this form, though, in this case, it might be better at if we multiplied both sides by -1 to get
0.02 times 0.7 = 0.014 all u needed to do was 2 times 7 and add two zeros
Answer:
y = -3x+2
Step-by-step explanation:
See attachment.
Find the slope:
Rise = (-4 - 5) = -9
Run = (2 - (-1)) = 3
Slope(Rise/Run) = -3
Find the y-intercept:
y = mx + b
y = -3x + b
5 = -3*(-1)+b [Use point (-1,5)
b = 2
====
y = -3x + 2
