ANSWER
B. f(x) = 3x - 8
EXPLANATION
We have the graph of a straight line given and we need to find the function that it represents.
A linear function is generally given as:
f(x) = mx + c
where m = slope
c = y intercept
So, we need to identify the slope and y intercept.
The y intercept is the point where the graph touches the y axis. From the graph, the y intercept is:
c = -8
Now, to find the slope, we use the formula:
where (x1, y1) and (x2, y2) are two points that lie on the graph.
Let us use the given points:
(0, -8) and (1, -5)
Therefore:
Therefore, the equation of the line is:
f(x) = 3x - 8
Answer:
What is the length of a line segment joining these points?

Answer:
yes
Step-by-step explanation:
tea is 1.20 a piece and cake is 1.50
1.50×4=6
1.20×3=3.60
6+3.60=9.60
Answer:
4y = 3
Step-by-step explanation:
To subtract the 2nd equation from the first, negate all three of the second equation terms: 3x + 2y = -4
and then add (combine) this result to (with) the first equation:
-3x + 2y = 7
3x +2y = -4
----------------------
4y = 3 (this is the desired result))
