C. a (2, 1)
b (5, 3)
c (4, -1)
a = -1 and b = 5
5a-7b+b2
5(-1) - 7(5) + 5^2
-5 - 35 + 25
-40 + 25
-15
-15 would be the result

Answer:
<h2>Graph b</h2>
Step-by-step explanation:
The equation of a linear function in slope-intercept form:

m - slope
b - y-intercept
The graph of linear function is a straight line therefore we need only two points to the plotting the graph.


Vicki is correct!
That is because they all took 2/6
so simplified they all took 1/3
Hope this helps ;)
X, 2x, and (x+2x)=3x
6x=180
x=30
30, 60, 90 triangle.
