7 0

Answer:

The answer is

y = 3x + 5

Step-by-step explanation:

❃Incase you forgot what the linear equation formula is ↶

y = mx + b

❃Since we already have the slope, we don't need to solve for that.

➊ First: We are going to find the y-intercept.

y = mx + b \\ 2 =  3( - 1) + b \\ 2 = - 3 + b \\ \frac{ + 3 = + 3 \: \: \: \: \: }{5 = b}

➋Second: Plug in.

y = 3x + 5

Determine the gear ratio for a bike with 45 front teeth and 18 rear sprocket teeth.
My name is Ann [436]

Answer:

The gear ratio is 2.5 :1.

Step-by-step explanation:

A gear ratio is the ratio of the teeth on the front sprocket and the teeth on the rear sprocket.

Given is that the bike has 45 front teeth and 18 rear sprocket teeth.

So, gear ratio will be \frac{45}{18}= \frac{5}{2}=2.5

Hence, the ratio is 2.5 :1.
