Writing Linear Equations Given Two Points

Question 1

The first step of writing an equation when given two points is the same for both strategies, slope-intercept or point-slope forms. What would be the first step in finding the equation of the line that passes through (5, 1) and (3, 5)?

find the slope

Question 2

m = -7✔ -21/22

Revolt · Accepted Answer

✔ -2

Question 3

b = -14-8✔ 27

Revolt · Accepted Answer

✔ 2

Question 4

y = (1/2)x – 8✔ y = -2x + 2y = 2x – 14y = -2x – 8

Revolt · Accepted Answer

✔ y = -2x + 2

Question 5

y = –3x + 5y = 3x – 5 y = one-third x + 3 y = negative one-third x + 5

Question 6

y = x + 67 = –1(–1) + by – 4 = –1 (x – 2)y – 7 = –1 (x – (–1))y – 2 = x – 4y = –x + 6

Revolt · Accepted Answer

y – 4 = –1 (x – 2); y – 7 = –1 (x – (–1)); y = –x + 6

Question 7

In which step did Helena make an error?

Revolt · Accepted Answer

In step 2, she didn’t use an x and y from the same coordinate pair.

Question 8

What can you conclude about the line represented in the table? Select all that apply.

Revolt · Accepted Answer

Using either slope-intercept or point-slope forms will result in the same equation.; The slope is .; The y-intercept is 0.
