Answer:
Technically not on a graph but on a table yes it matter but here if I were you I would do (2,2) and (-1,-4)
Step-by-step explanation: y=mx+b
(2,2) and (-1,-4) 2=2(2)+b Answer is: y=2x+(-2)
x1 y1 x2 y2 2=4+b
-4-2=-6 -2=b
-1-2=-3 y-intercept
m=2
slope
Answer:
14 cm squared
Step-by-step explanation:
The shaded triangle is clearly half of the rectangle, and half of 28 is 14.
The other way you can look at it is that the dimensions of the rectangle are 4 cm and 7 cm. The area of a triangle equation is 
. So 
is 14.
Isn't it a function considered a function if it has no intersecting lines? Maybe you should graph it and see if it has intersecting lines or not. If it doesn't the it's a function if
it does then it's not. I think..?
Vertex form is
y = a(x - b)^2 + c
here a = -3 and b = -18 so we have
y = a(x + 3)^2 - 18
when x = 0 , y= 0 ( the y-intercept) so:-
0 = a(3^)2 - 18
9a = 18
a = 2
so the parabola is y = 2(x + 3)^2 - 18
x intercepts found as follows:-
2(x + 3)^2 - 18 = 0
(x + 3)^2 = 9
x + 3 = +/- sqrt9 = +/- 3
so x intercepts are 0 and -6 Answer
