3.        2x - y = 10
    2x - 2x - y = -2x + 10
                 -y = -2x + 10
                 -1         -1
                   y = 2x - 10
   Slope: 2

4.        5x - 2y = 10
    5x - 5x - 2y = -5x + 10
                 -2y = -5x + 10
                  -2          -2
                    y = 2.5x - 5

5.    y - y₁ = m(x - x₁)
    y - (-2) = -3(x - (-1))
       y + 2 = 3(x + 1)
       y + 2 = 3(x) + 3(1)
       y + 2 = 3x + 3
           - 2         - 2
             y = 3x + 1

I REALLY NEED HELP QUICK!
Leni [432]

Answer:

y=1/2x-5

Step-by-step explanation:

From the picture you can see that (0, -5) is a point on the function and that (2, -4) is another point. Using these you can find the slope of the function with the equation

(y_{2} -y_{1})/(x_{2}-x_{1} )

We can substitute in the points so it looks like

(-4--5)/(2-0)  or  1/2 which is the slope of the function

Now, since the y-intercept is (0, -5) on the graph, the b part in the slope-intercept form of the equation would be -5, leaving us with the equation y=1/2x-5
