Answer:
y = 2x - 4
Step-by-step explanation:
Remember, the equation for a line in slope-intercept form is y = mx + b. m is the slope and b is the y-intercept.
To find the slope, find the distance between two points. For example, let's use (3, 2) and (4, 4). The line "rises" two units and "runs" one unit to the right. Since slope is always rise/run, m = 2/1, or 2.
To find the y-intercept on a graph, look at where the line touches a point on the y-axis. This point is (0, -4), therefore, the b = -4.
Plugging these values in, we get the final answer, y = 2x - 4.
