Answer:

see attached

Explanation:

Easy way: use a graphing calculator.

__

Manually: plot the y-intercept and another point.

The given equation is in slope-intercept form:

y = mx + b . . . . . . . slope m, y-intercept b

For this line, the slope is 2/3, and the y-intercept is 1.

This means the line crosses the y-axis at y=1. You can plot that point on your graph.

The slope of 2/3 means the line will rise 2 units for each 3 units to the right. 3 units right of the y-axis is x=3. 2 units up from y=1 is y=3. So, another point on the line is (x, y) = (3, 3). Plot that point and draw a line through the points you have identified.
