Given f(x) = 17-x^2what is the average rate of change in f(x) over the interval [1, 5]?

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula,equation,to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.

In what form is the following linear equation written y=9x+2
