A line passes through the points (3,17) and (9,23) Write a linear function rule in terms of x and y for this line.

A line passes through the points (4,17) and (7,20).
The linear function rule is y= 1x+13
Given :
A line passes through the points (4,17) and (7,20).
The linear function is y=mx+b where m is the slope
lets find out slope using formula

Slope of the line using the given points is 1
Lets pick any one point (4,17) and use slope to find function rule y
y=mx+b
x is 4 and y is 17 and m=1

Replace the value of 'b' and write the equation

The linear function rule is y= 1x+13
