The equation for the given table is y = x-1.
<u>Step-by-step explanation:</u>
Plot the points in the graph.
The formula for finding slope,
.
rise =
and run =
.
Here let us take two points (0,-1) and (1,0).
rise=0-(-1). and run =1-0.
rise= 1 and run 1.
m= 1.
∴ y=x+c.
From the data given the y is one less than x.
∴ y= x-1.
Answer:
One solution (-1,2)
Step-by-step explanation:
Since these two linear equations have different slopes, different y-intercepts, and are indeed linear, these equations will only have one crossing when graphed, and hence one solution.
To find that solution, we can simply set the equations equal to each other.
y = -x + 1
y = 2x + 4
-x + 1 = 2x + 4
-3 = 3x
-1 = x
Now plug that value back into one of the equations:
y = -x + 1
y = -(-1) + 1
y = 2
So now you know the crossing for these two equations occurs at (-1,2).
Cheers.
