What is the slope of this line?

y = 3x + 4

Step-by-step explanation:

The line passes through points (-3, -5) and (0, 4)

The slope of the line = change in y-axis ÷ change in x-axis

i.e the slope = = = 3

Taking another point (x, y) on the line,

The slope = = 3

Simplifying the equation above gives;

y - 4 = 3x

y = 3x + 4 (equation of the line)

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
