<h2>Explanation:</h2><h2></h2>

No graph has been provided, but I've provided the graph shown below. Recall that the slope intercept form of the equation of a line is given by:

$y=mx+b \\ \\ \\ Where: \\ \\ m:slope \\ \\ b:y-intercept$

First of all, the y-intercept of this graph lies on the point:

$(0,1)$

So our correct option could be either B) or C) because the y-intercept in those cases lies also on the point $(0,1)$ . If you lies on this point and walk 1 units horizontally, then the y-coordinate runs 3 units up until it gets point $(1,4)$ . Therefore, the slope of this line is $m=3$

In conclusion, this graph is represented by the equation:

B) y = 3x + 1

On a number line, point A has a coordinate of −6, and point B has a coordinate of 2. Which is the coordinate of point M, the mid

klasskru [66]

To solve this, we just need to find the distance between the points A and B in the number line, and then, divide that distance by 2.
Remember that the distance formula between tow point in the number line is:
$d=|x_{2}-x_{1}|$
From our point we can infer that $x_{1}=-6$ and $x_{2}=2$ , so lets replace the values:
$d=|x_{2}-x_{1}|$
$d=|2-(-6)|$
$d=|2+6|$
$d=8$

Now, to find the coordinate of the midpoint, we just need to divide that distance by 2:
$M= \frac{8}{2}$
$M=4$

We can conclude that the coordinate of the point M, the midpoint of AB, is 4

1. Given f(x)=2x 2 +1 and g(x)=3x-5 find the following

LenKa [72]

The value of the function 1) f -g = 2x² - 3x + 6 and 2) f(g(2)) is 3.

Here the two functions are given, f(x) and g(x).

f(x) = 2x² + 1

g(x) = 3x - 5

We have to find f-g and f(g(2)).

1) f- g

f(x) - g(x)

(2x² + 1) - ( 3x - 5)

2x² + 1 - 3x + 5

2x² - 3x + 6

2) f(g(2))

f(g(x)) = 2(3x-5)² + 1

= 2( 9x² - 30x + 25) + 1

= 18x² - 60x + 50 + 1

= 18x² - 60x + 51

f(g(2)) = 18(2)² - 60(2) + 51

=18× 4 - 120 + 51

= 72 - 120 + 51

= 123 - 120

= 3

Therefore the value of f-g is 2x²- 3x + 6 and the value of f(g(2)) is 3.
