I will be taking test 1 as soon as possible in the testing center at VHCC if that is okay. Thank you,

Very good.

For the function y = 1.1 x + .8, what are the coordinates of the x = x1 point, in terms of the symbol x1? What are the coordinates of the x = x2 point, in terms of the symbol x2?

What therefore is the rise between these two points, and what is the run?

What is the average slope of the graph between these two points? Be sure to simplify your result.

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution:

When x= x1 we get y= 1.1(x1) + .8

Y= 1.1x1 + .8

(x1, 1.1x1+.8)

when x=x2 we get y= 1.1(x2) + .8

y=1.1x2+.8

(x2, 1.1x2+.8)

The rise is (1.1x2+.8) - (1.1x1 + .8) = 1.1x2 - 1.1x1

The run is x2 - x1 = x2-x1

The slope 1.1x2 - 1.1x1 / x2-x1 = 1.1(x2-x1) / x2-x1 = 1.1

Given Solution:

In terms of the symbol x1 the coordinates of the x = x1 point are ( x1, 1.1 x1 + .8) and the coordinates of the x = x2 point are ( x2, 1.1 x2 + .8).

The rise between the two points is therefore

rise = (1.1 x2 + .8) - (1.1 x1 + .8) = 1.1 x2 + .8 - 1.1 x1 - .8 = 1.1 x2 - 1.1 x1.

The run is

run = x2 - x1.

The slope is therefore (1.1 x2 - 1.1 x1) / (x2 - x1) = 1.1 (x2 - x1) / (x2 - x1) = 1.1.

Question: `q002. For the function y = 3.4 x + 7, what are the coordinates of the x = x1 point, in terms of the symbol x1? What are the coordinates of the x = x2 point, in terms of the symbol x2?

What therefore is the rise between these two points, and what is the run?

What is the average slope of the graph between these two points? Be sure to simplify your result.

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution:

When x=x1 we get y= 3.4(x1) + 7

Y= 3.4x1 + 7

(x1, 3.4x1 + 7)

When x= x2 we get y= 3.4(x2) + 7

Y= 3.4x2 + 7

(x2, 3.4x2+7)

The rise is (3.4x2 + 7) - ( 3.4x1+7) = 3.4x2 - 3.4x1

The run is x2- x1

The slope is 3.4x2-3.4x1 / x2-x1 = 3.4(x2-x1) / x2-x1 = 3.4

Given Solution:

In terms of the symbol x1 the coordinates of the x = x1 point are ( x1, 3.4 x1 + 7) and the coordinates of the x = x2 point are ( x2, 3.4 x2 + 7).

The rise between the two points is therefore

rise = (3.4 x2 + 7) - (3.4 x1 + 7) = 3.4 x2 + 7 - 3.4 x1 - 7 = 3.4 x2 - 3.4 x1.

The run is

run = x2 - x1.

The slope is therefore (3.4 x2 - 3.4 x1) / (x2 - x1) = 3.4 (x2 - x1) / (x2 - x1) = 3.4.
