Question

The linear equation 20y – 30x = –900 relates the drone's elevation, y, in meters from the surface of the water to the number of seconds, x, that the drone travels. Graph the equation. What are the slope and y-intercept of the line?

Answer 1

The slope of the line is 3/2 and the y-intercept is -45.

Step-by-step explanation:

To graph the equation 20y - 30x = -900, we can rearrange it in slope-intercept form y = mx + b, where m is the slope and b is the y-intercept. Rearranging the equation, we have:

20y = 30x - 900

y = (30/20)x - 900/20

y = (3/2)x - 45

From this equation, we can see that the slope is 3/2 and the y-intercept is -45.
