Solution
Solution Steps
Step 1: Find two points on the line.
Two points on the line are (0, 3) and (4, 0).
Step 2: Calculate the slope.
The slope, m, is given by the formula:
m = (y2 - y1) / (x2 - x1)
Using the points (0, 3) and (4, 0):
m = (0 - 3) / (4 - 0)
m = -3/4
Step 3: Determine the y-intercept.
The y-intercept is the point where the line crosses the y-axis. In this case, it is (0, 3), so the y-intercept, b, is 3.
Step 4: Write the equation in slope-intercept form.
The slope-intercept form is y = mx + b. Plugging in the values we found for m and b:
y = -3/4x + 3
