What is the value of p if the gradient of the line joining (-1,p) and (p,4) is \(\frac{2}{3}\)?
A
-2
B
-1
C
1
D
2
correct option: d
\(\frac{y_1 - y_o}{x_1 - x_o}\) = m
\(\frac{4 - p}{p + 1}\) = \(\frac{2}{3}\)
2p + 2 = 12 - 3p
5p = 10
p = \(\frac{10}{5}\)
= 2
\(\frac{4 - p}{p + 1}\) = \(\frac{2}{3}\)
2p + 2 = 12 - 3p
5p = 10
p = \(\frac{10}{5}\)
= 2
