Answer:1367

Step-by-step explanation:Lets assume the amount spent on everything else be "x".

We know total cost can not exceed $2000.

∴ Forming an inequation to find the amount spent on everything else.

⇒

Now, solving it to find x

Subtracting both side by 637

⇒

∴

Hence, he can spend maximum of $1367 for eveything else.

What are the slope and y-intercept of the linear function graphed to the left? slope: –2; y-intercept: 2 slope: ; y-intercept: 1

Anon25 [30]

Let

$A(0,1)\\ B(2,0)$

we know that

The y-intercept is the y-coordinate of the point when the value of x is equal to zero

the y-coordinate of the point A is the y-intercept

$y=1$

The answer part a) is

The value of y-intercept is $1$

Part b) Find the slope m

we know that

the value of the slope is equal to

$m =\frac{(y2-y1)}{(x2-x1)}$

Substitute the values

$m =\frac{(0-1)}{(2-0)}$

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

therefore

the answer Part b) is

The value of the slope is equal to $-\frac{1}{2}$

The general answer is

The slope is $-\frac{1}{2}$

The value of y-intercept is $1$
