Given: The equation below
To Determine: The graph representing the equation using the slope and y-intercept
Solution
Step 1: Determine the y-intercept
To calculate the y-intercept, make x = 0
The coordinate of the y-intercept is (0, 3)
Step 2: Determine the x-intercept
To calculate the x-intercept, make y = 0
The coordinate of the x-intercept is (4.5, 0)
Step 3: Determine the slope
The general equation of a straight line is given as
Compare the general equation to the given equation
Use the coordinates of y-axis, x-axis and the slope to plot graph as shown below
