Use the image to answer the question.
An illustration shows the first quadrant of a coordinate plane titled Population of a City Since 1900.
The x-axis shows years since 1900 and ranges from 0 to 80 in increments of 10. The y-axis shows population per thousand and ranges from 0 to 80 in increments of 5. Nine points are plotted on the graph. The points are plotted at approximate coordinates left parenthesis 0 comma 20 right parenthesis, left parenthesis 10 comma 28 right parenthesis, left parenthesis 20 comma 30 right parenthesis, left parenthesis 30 comma 35 right parenthesis, left parenthesis 40 comma 47 right parenthesis, left parenthesis 50 comma 55 right parenthesis, left parenthesis 60 comma 57 right parenthesis, left parenthesis 70 comma 68 right parenthesis, and left parenthesis 80 comma 66 right parenthesis. An upward slanting line starts at left parenthesis 0 comma 20 right parenthesis and continues to left parenthesis 60 comma 57 right parenthesis.
The population growth of a city since 1900 is represented by a linear model. Interpret the slope and the y-intercept.

you sure??
Apologies for the confusion. Upon reviewing the information provided, the correct interpretation is:
For every 10 years since 1900, the population grew by approximately 10 per thousand. In 1900, the population was 20 per thousand.
So, the correct answer is:
For every 10 years since 1900, the population grew by approximately 10 per thousand. In 1900, the population was 20 per thousand.
To interpret the slope and the y-intercept of the linear model representing the population growth of the city since 1900, we need to analyze the information provided in the illustration.
Looking at the graph, we can see that there is an upward slanting line starting at (0, 20) and continuing to (60, 57). This line represents the population growth over time.
The slope of a line represents the rate of change. In this case, the slope represents the rate at which the population grows each year since 1900. To find the slope, we can use the formula: slope = (change in y) / (change in x).
From the graph, we can observe that the change in y is approximately 57 - 20 = 37, and the change in x is 60 - 0 = 60. Therefore, the slope is approximately 37 / 60 = 0.617.
The y-intercept of a line is the point where the line intersects the y-axis. In this case, the y-intercept represents the population in the year 1900. According to the graph, the y-intercept is (0, 20), indicating that the population in 1900 was approximately 20 per thousand.
Therefore, based on the information provided in the illustration, the correct interpretation is:
"For every year since 1900, the population grew by approximately 0.617 per thousand. In 1900, the population was 20 per thousand."
So the answer is "For every year since 1900, the population grew by approximately 0.617 per thousand. In 1900, the population was 20 per thousand."
