Answer:
B
Step-by-step explanation:
The formula for Y-intercept is y=mx+b.
b is your y-intercept so in your case the line would go through -4 on the y axis.
m is your slope and your slope is rise over run or y over x. In the equation your slope is 5/1 so 5 up and 1 right. After doing that you get your line after adding another point on the graph.
Number 2. It is not a function
the graphed equation is:
y = -|x| + 1

How to find the algebraic expression that matches the graph?</h3>
On the graph, we can see an absolute value equation, which opens downwards, and passes through the points (1, 0) and (0,1).
The general absolute value equation is:
y = a*|x - b| + c
Because the vertex is at the point (0, 1), we know that:
b = 0, c = 1
Replacing that we get:
y = a*|x| + 1
Now, this must be zero when we evaluate in x = 1, then:
0 = a*|1| + 1
a = -1
Then the graphed equation is:
y = -|x| + 1
