What is the slope (m) and y-intercept (b) of the following? y = mx + b

Question

y = 12x – 20

The number of cups of lemonade
made at a lemonade stand if 3 cups
are made every minute.

m = 13t

The height in x weeks of a giraffe that
grows 2 inches per week if its starting
height is 84 in.

answer all of them

Answer 1

For y = 12x - 20:
Slope (m) = 12
Y-intercept (b) = -20

For m = 13t:
This equation does not include a y-intercept, only the slope (m) which is 13. It is a linear equation that describes the number of cups of lemonade made over time.

For height in x weeks = 2x + 84:
Slope (m) = 2
Y-intercept (b) = 84

These are all linear equations described in the form y = mx + b.

Answer 2

what about The number of cups of lemonade
made at a lemonade stand if 3 cups
are made every minute.

Answer 3

For the number of cups of lemonade made at a lemonade stand if 3 cups are made every minute, the equation can be represented as:

y = 3m

Here, m represents the number of minutes passed and y represents the total number of cups of lemonade made. So, the slope (m) in this case would be 3 and there is no y-intercept in this equation.
