Find the equation of the line through the points (-5,11) and (2,-3)
y=

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?

For what values of a is the sum of the fractions 2a−1 / 4 and a−1 /3 positive?

If y varies as x, and y=8 as x=4 what will be the value of y if x=2
