The equation ab is y=2x + 4. write an equation of a line parallel to line ab in slop-intercept form that contains point (3,-2)

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.
