zero

undefined

positive

negative

Answer 1

\[slope = \frac{ y _{2} -y _{1} }{x _{2}-x _{1} }\]

Answer 2

so what is the answer

Answer 3

\[x _{1} = 1 , y _{1}= 2\]

Answer 4

the same goes for x2 and y2

Answer 8

The equation of line CD is (y−3) = − 2 (x − 4). What is the slope of a line perpendicular to line CD?

1 over 2

2

negative 1 over 2

−2

Answer 9

@VultureKV
The answer is What YOU come up wit if you apply the equation which @afifaRahman kindly gave you above

Put the values for x1,x2,y1 & y2 into that equation nd theanswer will be yours!

Answer 10

06.02 Slope
Warning: There is a checkbox at the bottom of the exam form that you MUST check prior to submitting this exam. Failure to do so may cause your work to be lost.

Question 1 (Multiple Choice Worth 4 points)

(06.02 MC)

Line QR contains (2, 8) and (3, 10) Line ST contains points (0, 6) and (−2, 2). Lines QR and ST are

parallel because the product of the slopes is −1

perpendicular because the product of the slopes is −1

parallel because the slopes are the same

perpendicular because the slopes are the same

Question 2 (Multiple Choice Worth 4 points)

(06.02 LC)

The equation of line CD is (y−3) = − 2 (x − 4). What is the slope of a line perpendicular to line CD?

1 over 2

2

negative 1 over 2

−2

Question 3 (Multiple Choice Worth 4 points)

(06.02 LC)

Line CD contains points A (4, 6) and B (−2, 6). The slope of line CD is

zero

undefined

positive

negative

Question 4 (Multiple Choice Worth 4 points)

(06.02 MC)

The equation of line QR is y = negative 1 over 2x + 1. Write an equation of a line perpendicular to line QR in slope-intercept form that contains point (5, 6).

y = 2x + 16

y = negative 1 over 2x + 17 over 2

y = − 1 over 2x + 7 over 2

y = 2x − 4

Question 5 (Multiple Choice Worth 4 points)

(06.02 MC)

The equation of line CD is y = −2x − 2. Write an equation of a line parallel to line CD in slope-intercept form that contains point (4, 5).

y = −2x + 13

y = negative 1 over 2x + 7

y = 1 over 2x + 3

y = − 2x − 3
