#10:  Write the slope-int. form of the eq'n thru (-2,-3) and (-2,-1).
                                         change in y       -1 - (-3)            2
First, find the slope.  m = ----------------- = -------------- = -----------
                                         change in x        -2 - (-2)           0

We can NOT divide by zero, so the slope here is undefined.  That means that the graph of the line thru these 2 points is a VERTICAL one with no y-intercept.

Since both points are on the line whose x-coordinate is -2, that's the equation of the line:

x = -2.

Two bikers, Derek and Tina, start riding from the same location. Derek rides due west for x miles. Tina goes due south and cover
kirza4 [7]

Answer: Tina rides 4 miles and Derek rides 3 miles.

Explanation:

Since we have given that

Distance covered by Derek in west direction be x

Distance covered by Tina in south direction be x+1

Distance between the bikers when they both stop is x+2

Since it forms right triangle, so we will apply "Pythagorus theorem":

H^2=P^2+B^2\\\\(x+2)^2=x^2+(x+1)^2\\\\x^2+4x+4=x^2+x^2+1+2x\\\\x^2+4x+4=2x^2+2x+1\\\\x^2-2x^2+4x-2x+4-1=0\\\\-x^2+2x+3=0\\\\x^2-2x-3=0\\\\x^2-3x+x-3=0\\\\x(x-3)+1(x-3)=0\\\\(x+1)(x-3)=0\\\\x=-1,3

Since distance can't be in negative sign, so we take x=3 miles

Derek rides 3 miles

Tina rides is given by

x+1=3+1=4\ miles

Hence, Tina rides 4 miles and Derek rides 3 miles.
