Answer:

Step-by-step explanation:
Let's write the equation of the line in the slope-intercept form. That is, y= mx +c, where m is the slope and c is the y-intercept.
Identify 2 coordinates on the line to calculate the slope.
The 2 points are (1, 2) and (4, 4).
Slope

= 
= 
Substitute the value of the slope into m:

Substitute any point into the equation to find c:
When x= 1, y= 2,

Solve for c:

c= 
Thus, the equation that represents the line is
.
