1. Find the y-intercept. –x + 2y = 2 2. Write the equation of the line with x-intercept (–6, 0) and undefined slope. 3. A roof rises 9.5 ft over a horizontal distance of 14.72 ft. What is the slope of the roof to the nearest hundredth?

A roof rises 9.5 ft over a horizontal distance of 14.72 ft. What is the slope of the roof to the nearest hundredth? 1.) y = mx + b: 2y = 2 + x y = 1 + (1/2)*x Or, y = (1/2)*x + 1; you should be able to figure this out now. 2.) The slope is underfined when the line is vertical: x = -6 3.) Hint: slope is change in y over the change in x Rise over run. Draw a picture.
