Question

What is the answer for this

Answer 1

Answer:  $y=\frac{1}{30}x+1$

Step-by-step 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:

$m=\frac{y_2-y_1}{x_2-x_1}$

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

Then, substituting into the formula:

 $m=\frac{2-3}{30-60}=\frac{1}{30}$

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:

 $y=\frac{1}{30}x+1$

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