How can you write the equation for a linear function if you know only two ordered pairs for the function?
dedylja [7]

Answer:

See below

Step-by-step explanation:

We first have to understand the parts of a y=mx+b equation

y=mx+b

m: Is the slope

b: Is the y-intercept

x: is the x part of (x,y)

y: is the y part of(x,y)

So...

if we use an example ordered pair like (1,3)

and a slope of 2

We can plug everything into y=mx+b to get

1=2*3+b which simplifies to  b= -5

Now, you can use this concept to fill in the blanks below:  

Use the two ordered pairs to find the slope, (m).

Then substitute the slope, and (one set of ordered pairs) into y=mx+b to solve for (b).

<u><em>(5 × 20%) × y = 10 × 5</em></u>

<u><em>y = 50</em></u>
