Answer:
Option D
Step-by-step explanation:
Rate of change of a linear function between two points 
and 
is given by,
Rate of change 'm' = 
From the given table,
Rate of change of the function between (-2, 6) and (-4, 9),
Rate of change 'm' = 
m = 
Initial value = y-intercept
Let the equation of the line passing through a point (h, k) is,
y - k = m(x - h)
If a point (-2, 6) is lying on the graph of the function,
y - 6 = 
y = 
y = 
Y-intercept of the function = 3
Therefore, initial value of the function = 3
Option D is the answer.
Well if you have the coordinates (2,2) and (4,4) you plug in the y from the second cords for y2
So it would be 4-2/4-2 and 2/2 equals 1
1 would be the m in y=MX+b
Then plug one set of coords in y=MX+b
2=1x+b
I know it's confusing to understand but I tried lol

Step-by-step explanation:
Answer:
Width = x² + 5x - 4
Step-by-step explanation:
By the definition of an area model,
Area = Width × greatest common factor
Since, Area = 4x² + 20x - 16
And greatest common factor = 4
4x² + 20x - 16 = 4(Width)
By dividing both the sides of the equation by 4,
x² + 5x - 4 = Width
Therefore, width = (x² + 5x - 4) will be he answer.
Answer:
$2.75 = cost of a hot dog
$4.50 = cost of a cheeseburger
Step-by-step explanation:
Let x = cost of a hot dog
y = cost of a cheeseburger
(1) 2x + 4y = 23.5 (2) 5x + y = 18.25
y = 18.25 - 5x
2x +4(18.25 - 5x) = 23.5
2x + 73 - 20x = 23.5
-18x + 73 = 23.5
-18x = -49.5
x = 2.75 y = 18.25 - 5(2.75)
y = 18.25 - 13.75
y = 4.50
$2.75 = cost of a hot dog
$4.50 = cost of a cheeseburger
