Answer:
y = 2x +4
Explanation:
The slope-intercept form of the equation of a line is ...
y = mx + b
where m represents the slope (rise/run), and b represents the y-intercept.
Here, the line increases by 2 units (rise=2) for each increase of 1 unit in the x-direction (run=1). Then the slope is ...
m = rise/run = 2/1 = 2
The graph crosses the y-axis at y=4, so the y-intercept value is ...
b = 4
Putting these values into the above slope-intercept form, we have ...
y = 2x + 4
