Answer:


Step-by-step explanation:

Answer:

Point-slope form:

y

4

=

2

(

x

+

3

)


Slope-intercept form:

y

=

2

x

2


Step-by-step explanation:

Assuming you mean a line that passes through these two points, use point-slope form:

y

y

1

=

m

(

x

x

1

)


To find the slope, m, use the slope formula

m

=

y

2

y

1

x

2

x

1


(-3,4) and (1,-4):

m

=

4

4

1

+

3


m

=

8

4

=

2


Now, plug in the slope and either point into point-slope form:

y

4

=

2

(

x

+

3

)


To convert this to slope intercept form, isolate y and simplify:

y

4

=

2

x

6


y

=

2

x

2
