1. For each pair of points, find a linear equation whose graph will go through the two points. Use x to represent the first coordinate and
y to represent the second coordinate.
a. (4,9) and (6, 13)
b. (5, 13) and (3,7)
c. (8,8) and (20, 14)
d. (-2,5) and (1, -4)

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.
