PLEASE HELP!!<br><br> What is the slope of the line on the graph?
Amanda [17]

Answer:

Slope = (-1/3)

Step-by-step explanation:

Point 1: (-6, 6); Point 2: (6, 2)

            (x₁, y₁)                (x₂, y₂)          

        y₂ - y₁         2 - 6          -4            -4 ÷ 4         -1

m = ------------ = ----------- = ---------- = -------------- = -------

        x₂ - x₁        6 - (-6)      6 + 6        12 ÷ 4           3

y - y₁ = m(x - x₁)

y - 6 = (-1/3)(x + 6)

y - 6 = (-1/3)x - 2

   +6              +6

-------------------------

y = (-1/3)x + 4

I hope this helps!

Solve the equations<br> x squared + y squared = 36<br> x = 2y + 6
djyliett [7]

Answer:

Given the equations:

x^2+y^2 =36              .....[1]

x =2y +6                     ....[2]

Substitute the value of x in [1] we get;'

(2y+6)^2+y^2 =36

Use identity: (a+b)^2= a^2+2ab+b^2

4y^2+36+24y + y^2 =36

Combine like terms;

5y^2+36+24y=36

Subtract 36 from both sides we get;

5y^2+24y=0

y (5y+24) = 0

By zero product property, we get;

y = 0 and y =- \frac{24}{5} = -4.8

Substitute these y values in [2] to get x values;

For y = 0 we have;

x = 2(0) +6 = 0+6 = 6

For x = -4.8

x = 2(-4.8)+6 = -9.6 + 6 = -3.6

Therefore, the solution for the given equations are; (6, 0) and (-3.6, -4.8)
