1. The function of this graph is f(x) = 0.5x + -2
Plug (-2) into the x variables so it looks like:
f(-2) = 0.5 (-2) + -2
Then solve.
Answer: f(-2) = -3
**I'm not as sure about this one, so I might be wrong
2.
For #8, the y-intercept is 4 (you're right) and it represents the initial distance before she started hiking (D)
I tried to figure #9 out, but I couldn't find the answer. I came across a website that might help though: https://sciencing.com/determine-practical-domain-range-10052000.html
**I can't see #s 6 or 7
16 dimes = $1.60
<em>12 quarters</em><em> </em>= $3.00
The answer is the first one, A
Answer:
y = 3x+9
Step-by-step explanation:
The standard form of equation of a line is in the form y = mx + c
m is the gradient
c is the y intercept
Get the y-intercept
Substitute m = 3 and the point (-2, 3) into the formula y = mx+c
3 = 3(-2) + c
3 = -6+c
c = 3+6
c = 9
Get the required equation;
y = 3x + 9
Hence the required equation is y = 3x+9
