Question

HELP ME!

A line passes through the points (5,16) and (7,18) Write a linear function rule in terms of x and y for this line.

Answer 1

y=x+11；

Explanation:

Let's say the direct equation is y=kx+b;

Plug in the two points to get the system：

`\left \{ {{16=5k+b} \atop {18=7k+b}} \right.`

So k is equal to 1, b is equal to 11，

so y=x+11；
