The slope-intercept form:

m - slope
b - y-intercept
<em>subtract x from both sides</em>
<em>change the signs</em>

It's a linear function.
We need only two points to plotting a graph.
We choose any three values of x and calculate y.

Answer:
B
Step-by-step explanation:
Not counting human error he should get exactly eight questions right using scicence, but since it is random there is margin of error that may disfigure the outcome.

Pretty sure it’s 4. Hope this helped :)
Answer:
y= -7
Step-by-step explanation:
I'm not sure if this is what you are looking for but here you go!
If the equation is set equal to zero.
2+(5+y)=0 This is the original expression, we need to find the value for y.
5+y= -2 We move the two to the right to remove it from the left side of
the equation.
y= -7 We repeat the same thing as we did in the last step, except
with the value 5. This then gives us our y-value, which is -7.
I hope this helps!
