The equation of line WX is y = −2x − 5. Write an equation of a line perpendicular to line WX in slope-intercept form that contains point (−1, −2). (4 points) a. y = 1 over 2 x + 3 over 2 b. y = negative 1 over 2 x + 3 over 2 c. y = 1 over 2 x − 3 over 2 d. y = − 1 over 2 x − 3 over 2

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?
