Question

Plz help, it a question on a test due soon.

Look at the graph shown:



Which equation best represents the line?

y = 1 over 3. x − 1
y = 3x − 1
y = −x + 1 over 3.
y = 3x + 1

Answer 1

y=3x+1

Explanation:

The slope-intercept form is

y

=

m

x

+

b

, where

m

is the slope and

b

is the y-intercept.

y

=

m

x

+

b

Find the values of

m

and

b

using the form

y

=

m

x

+

b

.

m

=

3

b

=

1

=

m

x

+

b

.

m

=

3

b

=

1

The slope of the line is the value of

m

, and the y-intercept is the value of

b

.

Slope:

3

y-intercept:

1

Answer 2

The answer is y=1*-1
