Answer:
The way to calculate viewing area would be base multiplied by height, but if you would be more specific I would provide a more in detail answer.
The first one is X = 24 & the second one is x= 20
Y=mx+b is Slope Intercept Form, where m represents the slope and b represents the y-intercept.
The y-intercept is the value of y when x equals 0, and can be visualized on a graph as the point on the line when it crosses the y-axis.
