Formula for slope-intercept is y = mx+b. The y-intercept is the point where the line crosses the y-axis. From there on, use the slope to graph the line. For example, if the equation is y = 5x - 2, you would want to plot (0,-2) first on the graph. Then, continue using the slope, which is 5. Slope is rise/run. In this case, you go up five, then to the right one, since there is always an invisible one if the slope is a whole number.
Hope that helped. :)

Answer:
- Let p be the population at t be the number of years since 2011. Then,
- The projected population of the high school in 2015=1800
- In <u>2019</u> the population be 1600 students
Step-by-step explanation:
Given: The population at Bishop High School students in 2011 =2000
Also, Every year the population decreases by 50 students which implies the rate of decrease in population is constant.
So, the function is a linear function.
Let p be the population at t be the number of years since 2011.
Then,
So at t=0, p=2000
In year 2015, t=4, substitute t=4 in the above equation ,we get
Hence, the projected population of the high school in 2015=1800
Now, put p=1600 in the function , we get
Now, 2011+8=2019
Hence, in <u>2019</u> the population be 1600 students
