Hi!


First, we need to find the slope.


Here's the equation to find the slope.


(y2-y1)/(x2-x1)

Put in the values and solve.


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


-(4)/(6)

Simplify


-(2)/(3)


Now our equation is


y=-(2)/(3)x+b

We need to find b. Do this by putting one of the coordinates into the equation then solving.


3=-(2)/(3)*3+b

3=-2-b

5=b


y=-(2)/(3)x+5


The answer is 3)
y=-(2)/(3)x+5


Hope this helps! :)

(-3, 7) and (3 , 3)

Slope = (7 - 3)/(-3 - 3) = -4/6 = -2/3


y = mx + b

b= y - mx

b = 3 - (-2/3)(3)

b = 3 + 2

b = 5


Equation

y = -2/3 x + 5


Answer

3) y = -2/3 x + 5
