Determine the linear equation from the graph below. 1 height of a balloon 3 + . . . height (1000 ft) 10 20 30 40 50 60 time (sec)

Step-by-step explanation:

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

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

The slope of the line can be calculated with this formula:

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

Then, substituting into the formula, you get:

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

Substituting the slope and the y-intercept found into  , you get the equation of this line:

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

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
