(need 2 points) c. Use the graph to estimate the cost of service in a month when 20 calls were made. c = 5 + .25n Slope-Intercept Form y = mx + b slope y-intercept where the line crosses the y axis rise run A linear equation written in the form y = mx + b is in slope-intercept form.
• The graphing calculator can also create the equation of a line given two points on the line. The calculator uses a statistics feature called a "Linear Regression" to give you the slope and y-intercept of y = ax + b (the calculator's version of y = mx + b). Follow the link in the last box below to see how this works.

Based on the definition of vertical shift, the graph of y 1 (x) should look like the graph of f (x), shifted down 8 units. Take a look at the graphs of f ( x ) and y 1 ( x ). The graphical representation of function (2), g ( x ), is a line with a slope of 4 and a y -intercept at (0, -1).
The 95% confidence interval for the X-intercept is not symmetrical around the X-intercept. It goes further in one direction than the other, as illustrated in the graph below. Follow the Y=0 baseline from left to right. The region between the 95% confidence bands for the best fit line (blue curves) is the 95% CI of the X intercept.
(It easy to verify that the line defined by this equation has x 0 and y 0 as intercept values). Two-point form. Given two different points (x 1, y 1) and (x 2, y 2), there is exactly one line that passes through them. There are several ways to write a linear equation of this line.

Comparing this to y = mx + b (the equation of a straight line), we can see that if the period vs. the length of the pendulum were plotted on a graph with logarithmic axes, then the slope of the line would equal n and the y-intercept would be equal to the value of log10 k.
