Slope: 0<br> y-intercept: -2<br> .
Nookie1986 [14]

Answer:

The linear equation is the equation of straight line. where m is the slope of the line and c is the y-intercept. Thus, the y-intercept is expressed as (0, c). That is where the graph intercepts the y-axis (thus, the x value would be 0).

The total weight of a truck and its load is w pounds. Let /be the weight of the load . When it's empty the truck weighs 2,439 po
emmainna [20.7K]

Answer:

equation will be 2439+/=w

Step-by-step explanation:

It is pretty clear from the question, that

the weight of the load is /. and the weight of the empty truck is 2439 pounds.

It means when we load the truck with '/' pounds load, trucks weight increases and is given by

w = 2439 + /

For Example:

Suppose if load / = 1000 pounds it means weight of the truck after adding the load will be

w=2439+1000=3439 pounds.

The following graph of f(x) = x2 has been shifted into the form f(x) = (x − h)2 + k: a parabola with a vertex of 4, negative 2
Fiesta28 [93]
V(4,-2)

In the vertex form, the h value is the x and the k value is the y.
So if the vertex (4,-2) is also (h,k)

You can just simply replace the h and k in (x-h)^2+k.
Which gives us...
f(x)=(x-4)^2-2.

Quick algebra 1 question for 10 points!
Elodia [21]

y = mx + n

m =  \frac{y - y}{x - x}  =  \frac{5 - ( - 1)}{ - 5 - ( - 3)}  =  \frac{6}{ - 2}  =  - 3

y =  - 3x + n \\

<h3>Since both ( -3 , -1 ) and ( -5 , 5 ) pass through the line, they both satisfy its equation. Substitute any point in the new equation, I will choose ( -5 , 5 )</h3>

5 =  - 3( - 5) + n \\ n = 5 - 15 =  - 10

y =  - 3x - 10
