To find the rate of change, we can use the formula:
Rate of change = (change in y)/(change in x)
Using the given data, we can calculate the changes in x and y:
Change in x = -1 - (-2) = 1
Change in y = 70 - 80 = -10
Rate of change = (-10)/(1) = -10
The y-intercept can be determined by finding the value of y when x equals zero. In this case, we do not have x=0 in the given data. Therefore, we cannot determine the y-intercept.
To find the equation of the line, we can use the slope-intercept form:
y = mx + b
Where m is the rate of change, and b is the y-intercept (which we cannot determine in this case).
The equation of the line is y = -10x + b. However, since we do not have the value of b, we cannot determine the exact equation of the line.
X: -2, -1, 2, 5. Y: 80, 70, 40, 10. Answer the questions using the table. (3 points) the rate of change =___ the y−intercept = ___the equation of the line is ____
