Question

Equation for (3,-4) (-1,4)

Answer 1

Answer:

Step-by-step explanation:

Answer:

Point-slope form:

y

−

4

=

−

(

x

+

3

)

Slope-intercept form:

y

=

−

2

x

−

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

−

y

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

m

=

−

m

=

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
