State the slope and y intercept of the graph of 9-x=2y

1 answer:

8 0

The equation of a line is given by y = mx + c; where m is the slope.
The given equation is 9 - x = 2y
y = -1/2 x + 9/2
Therefore, the slope is -1/2 and the y-intercept is 9/2.

Line m includes the points (-3, 3) and (-4,-6). Line n has the same slope as line m and

Sveta_85 [38]

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut-off point with the y axis

The slope of a line is given by:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}$

We have that the line m passes through the following points:

$(x_ {1}, y_ {1}): (-3,3)\\(x_ {2}, y_ {2}): (-4, -6)$

So, the slope of the line m is:

$m = \frac {-6-3} {- 4 - (- 3)} = \frac {-9} {- 4 + 3} = \frac {-9} {- 1} = 9$

Line n has the same slope so the equation is of the form:

$y = 9x + b$

We have as data that the y-intercept is $-\frac{2} {3}$ . Thus, we have that the equation of line n is:

$y = 9x- \frac {2} {3}$

ANswer:

$y = 9x-\frac {2} {3}$

H(1) =<br> can someone help my brother ?

Fantom [35]

Answer:

h(1) = -2

Step-by-step explanation:

What h(1) is saying is the value of x = 1. We need to find the y-value.

We see from the graph that when x = 1, y = -2.
