Simplify the expression. (Will mark if correct)

9a + 3b − 4a − 2b

A) 5a − 7b
B) 5a + b
C) 13a + 7b
D) 13a − b

The answer is B) 5a + b

Step-by-step explanation:

9a - 4a is 5a

3b - 2b is 1b or just b therefore the answer is

5a + b

Yo sup??

given expression=9a+3b-4a-2b

(taking like terms together)

=9a-4a+3b-2b

=5a+b

Therefore the correct answer is option B

Hope this helps

The answer to your question is    y = -2x + 11

Step-by-step explanation:

A (1, 9)

B (3, 5)

- Find the slope

        m = - 2

- Find the line equation

        y - y1 = m (x - x1)

        y - 5 = -2(x - 3)

        y - 5 = -2x + 6

        y = -2x + 6 + 5

        y = -2x + 11
