Hi there!

\large\boxed{2, -9}

We can create an equation for the line PR using the given coordinates. Use the following formula for the slope:

m = \frac{y_2-y_1}{x_2-x_1}

Plug in the coordinates for P and R:

m = \frac{-5-(-1)}{-1-(-4)} = -\frac{4}{3}

Find the equation by using point-slope form:

y - y1 = m(x - x1)

Plug in a coordinate and the slope:

y - (-5) = -4/3(x - ( - 1))

Simplify:

y + 5 = -4/3(x + 1)

To find the y-coordinate if x = 2, plug in the x value:

y + 5 = -4/3(2 + 1)

y + 5 = -4/3(3)

y + 5 = -4

y = -9

Thus, the coordinate is (2, -9)

mylen [45]

Answer:

x=1, x=8

Step-by-step explanation:

4x2−36x+32=0

Step 1: Factor left side of equation.

4(x−1)(x−8)=0

Step 2: Set factors equal to 0.

x−1=0 or x−8=0

 (+1)        (+8)

x=1 or x=8
