The points (-15, r) and (-3, 16) lie on a line with slope 5/4. Find the missing coordinate r.
Setler79 [48]

Answer:

r = 1

Step-by-step explanation:

we know that :

Slope=\frac{y_{B}-y_{A}}{x_{B}-x_A}

Then

\frac{5}{4} =\frac{16-r}{-3-(-15)}

Then

\frac{5}{4} =\frac{16-r}{12}

Then

5×12 = 4×(16-r)

Then

60 = 64 - 4r

Then

4r = 64 - 60

Then

4r = 4

Then

r = 1

b = 6
c = 3

x = \frac{-6 +/- \sqrt{6^{2} -4*2*3} }{2*2}

x = 0.634 or x = -2.366
