Answer:

Explanation:

In order to find the equation of a line, you must first find the slope and y-intercept point.

Remember, the equation for a line is.

y = mx+b

m = slope

b = y-intercept

To find slope

m = y2-y1/x2-x1

x1 , y1 x2, y2

(-3, 7) (4, -7)

/ = divided by

Plug those values into slope equation

(-7 - 7)/(4 - (-3))

= -14/7

m = -2

so now we know the slope; -2

y = -2x+b

Now lets find b:

Plug in any point on the line, lets use (-3, 7)

-3 is x

7 is a y

y = mx + b

7 = (-2)(-3) + b

7 - 6 = b

b = 1

So the final equation is

y = -2x + 1
