Final answer:
The slope of a linear function measures how steep the line is and can be found by calculating the change in y divided by the change in x. The y-intercept is the point where the line crosses the y-axis, and can be found by looking for the value of y when x is 0.
Step-by-step explanation:
The slope of a linear function is the rate of change of the dependent variable with respect to the independent variable. In other words, it measures how steep the line is. To find the slope, you need to calculate the change in the y-values divided by the change in the x-values between any two points on the line. The y-intercept is the point where the line crosses the y-axis, which is the vertical axis. It is the value of y when x is 0.
For the line given in the table, you can identify the slope by finding the change in y divided by the change in x between any two points. To find the y-intercept, look for the value of y when x is 0 in the table. For the line given by the equation, you can identify the slope by looking at the coefficient of x. The y-intercept is the constant term in the equation.
