For all real values of m, 8 + 3(m - 5) =?
1 answer:
Answer:
We have the value as 3m-7
Step-by-step explanation:
It is given that we have the real number m. Now we are required to find the simplified form or the value of the expression:
Thus we can write it as:
Here we have to use the property:
So now we have:
So this is the required final value of the expression.

Part A
The graph is shown below as an attached image.
The diagram shows a straight line that goes through the two points (0,-3) and (1, -5)
I'm using GeoGebra to graph the line.
side note: (0, -3) is the y intercept which is where the graph crosses the y axis.
==================================================
Part B
Answer is choice 2
The graph can be written in the form y = mx+b, so it is linear
In this case, m = -2 is the slope and b = -3 is the y intercept
We can write the slope as m = -2 = -2/1. This tells us that we can move down 2 units and then over to the right 1 units to get from point to point. This process of "down 2, over to the right 1" happens when moving from point A to point B in the diagram below.
