Answer:

The answer to your question is -3

Step-by-step explanation:

Data

A (-8, -35)

B (6, 21)

Process

1.- Calculate the slope

slope = m = (y2 - y1) / (x2 - x1)

x1 = -8  y1 = -35   x2 = 6   y2 = 21

-Substitution

            m = (21 + 35) / (6 + 8)

-Simplification

            m = 56 / 14

-Result

            m = 4

2.- Calculate the equation of the line

            y - y1 = m(x - x1)

-Substitution

            y + 35 = 4(x + 8)

-Simplification

            y + 35 = 4x + 32

            y = 4x + 32 - 35

-Result

             y = 4x - 3

3.- Find the y-intercept

The y-intercept is the number after the x, for this equation is -3.

Write the equation of the line that is per to x = -3 and passes through the point (4,-7)
Anon25 [30]

Answer:

y=-1/3x-17/3

Step-by-step explanation:

I assume you mean <em>perpendicular</em><em> </em>to x=-3.

In that case, we would flip and take the negative. A perpendicular slope would be x=-1/3

Now we plug the point (4,-7) into the equation

y=mx+b

y=-1/3x+b

-7=-1/3*4+b

-7=-4/3+b

b= -17/3

The whole equation would be:

y=-1/3x-17/3

<em>I hope this helps! :)</em>

Can someone pleaseee help me
Nookie1986 [14]

Answer:

120 degrees

Step-by-step explanation:

Ok, so if you know that 5 is 120 degrees then 1 is 120 degrees because the angles will be corresponding when it is a set of lines that are parallel bisected by a line. So 1 is corresponding to 5 and 2 to 6 and 3 to 7 and 4 to 8.
