ANSWER and EXPLANATION
We are given the equation:
Since we are not given the domain and range, an easy way to graph it is to find the x and y intercepts and use those points.
To find the x intercept, we have to make y = 0:
=> 0 = (2/5)x - 6
=> (2/5)x = 6
x = (6 * 5) / 2
x = 15
So, the x intercept is (15, 0)
To find the y intercept, we have to make x = 0:
y = (2/5) * 0 - 6
y = -6
So, the y intercept is (0, -6)
Use these points to plot the graph:
