Introduction to Line and Angles

#### What is the measure of an angle that measures more than 0 degrees but less than 90 degrees? 1. [x] Acute angle 2. [ ] Obtuse angle 3. [ ] Right angle 4. [ ] Straight angle #### If two lines intersect to form congruent angles, what is the type of angle created? 1. [ ] Acute angle 2. [x] Right angle 3. [ ] Obtuse angle 4. [ ] Straight angle #### Which of the following is the formula for calculating the slope of a line if you are given two points, (x1, y1) and (x2, y2)? 1. [ ] Slope = y2 - y1 / x2 + x1 2. [x] Slope = y2 - y1 / x1 - x2 3. [ ] Slope = y2 + y1 / x2 - x1 4. [ ] Slope = y2 - x1 / y1 - x2 #### What is the value of the y-intercept if the equation of a line is y = -2x + 4? 1. [x] (0, 4) 2. [ ] (2, 0) 3. [ ] (4, 0) 4. [ ] (0, -2) #### If a line has a slope of 3/4, what is the rise over run of the line? 1. [x] 3/4 2. [ ] 4/3 3. [ ] 3 4. [ ] 4
