Answer:

y=2x+3

Explanation:

Because the y-intercept starts at 3 and it goes up by 2 and to the side 1 so it would be y = 2x +3

Answer: y = 2x + 3

Explanation:

We will write the equation in slope-intercept form.

y = mx + b

The slope can be found with "rise over run" since we have clear points on the graph.

Start at (0, 3), count up 2 units, and count one unit to the right. This gives us a slope of positive 2.

Rise / run = 2 / 1 = 2

The "b" value is where the line hits the y-axis. It hits the y-axis at y-coordinate 3, so our y-intercept is positive 3.

Final equation:

y = 2x + 3
