If you were to write the equation of this line in the form y=mx+c what is the value of m
1 answer:
Answer:
B choice.
Step-by-step explanation:
The graph decreases. Therefore, the slope is in negative. We can rule out A and C choices.
It is very obvious to tell because of steepness. Low steepness = low value
High steepness = high value.
We can also find the slope by using rise/run.
The change of y over the change of x.
Given the coordinate points (0,1) and (4,0). Both points are part of the graph.
Therefore the value of m is - 1/4

The solution is x = 4 and y = -1
Step-by-step explanation:
The system of equation is:
- y =
x - 3
- y = x - 5
To solve it using the elimination method do that
∵ y = x - 3 ⇒ (1)
∵ y = x - 5 ⇒ (2)
- Subtract equation (1) from equation (2) to eliminate y
∵ y - y = (x - x) - 5 - (-3)
- Remember (-)(-) = (+)
∴ 0 = x - 5 + 3
∴ 0 = x - 2
- Add 2 to both sides
∴ 2 = x
- Multiply both sides by 2
∴ 4 = x
∴ x = 4
- Substitute the value of x in equation (1) or (2) to find y
∵ y = 4 - 5
∴ y = -1
The solution is x = 4 and y = -1
