What is the equation of the line in slope-intercept form?

y = –10x – 2

y = –1x – 8

–8 = –2x – 1

y = –2x – 10

b =

-9

Use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. | Write the equation in slope-intercept form, y = mx + b.

y = –2x + 21

y = 2x – 9

y = 0.5x + 2

y = 2x + 7

m =

- 2

- 1

0.5

In which step did Samuel make an error?

In step 1, he substituted the x values for y and the y values for x.

In step 2, he made an arithmetic error.

In step 3, he substituted the wrong values for m and b.

Samuel did not make an error.

Choose the equation of the line.

y = –3x – 13

y = –3x – 5

y = –3x + 5

y = + 13

What can you conclude about this line? Select all that apply.

It is a vertical line.

It is a horizontal line.

The equation is x = –4.

The equation is y = –4.

It is impossible to have m = 0.
