Question

What is the answer for this

Answer 1

Answer:
`y=(1)/(30)x+1`

Explanation:

The equation of the line in Slope-Intercept form is:

`y=mx+b`

Where "m" is the slope and "b" is the y-intercept.

You need to find slope of the line with the formula:

`m=(y_2-y_1)/(x_2-x_1)`

Pick to points of the given line. You can choose the point (60,3) and the point (30,2).

Then, substituting into the formula:

`m=(2-3)/(30-60)=(1)/(30)`

You can observe in the graph that the line intercepts the y-axis at the point (0,1), therefore "b" is:

`b=1`

Substituting the slope and the y-intercept found into
`y=mx+b`, you get the equation of this line:

`y=(1)/(30)x+1`

Where "y" represents the Height (1,000 ft) and "x" represents the Time in seconds.
