ANSWER

D) (a + 1, b + m)

EXPLANATION

The given line passes through (a,b) and has slope m.

The equation is:

$y - b = m(x - a)$

When x=a+1, we obtain

$y - b = m(a + 1 - a)$

This

$y = m( 1 ) + b$

$y = m + b$

Therefore,(a + 1, b + m) must also lie on this line.

The correct answer is D.

Answer:

$a.\ 12$

Step-by-step explanation:

$\frac{5}{6}y-8=2\\\\Add\ 8\ both\ sides\\\\\frac{5}{6}y-8+=2+8\\\\\frac{5}{6}y=10\\\\Multiply\ by\ 6\ both\ the\ sides\\\\\frac{5}{6}y\times 6=10\times 6\\\\5y=60\\\\divide\ by\ 5\ both\ the\ sides\\\\\frac{5y}{5}=\frac{60}{5}\\\\y=12$
