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).

Answer: Slope: -1    Y-intercept: -4

Step-by-step explanation:

Slope formula:

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

m=\frac{-13 -(-6)}{9-2}= m=\frac{-13 + 6}{9-2}  

m=\frac{-7}{7\\}

m = -1

When you draw this on the graph, the y-intercept is -4.

y = -4
