What is the equation in point slope form of the line that passes through the point(–1, –3) and has a slope of 4?

y−1=4(x−3)

y+1=4(x+3)

y−3=4(x−1)

y+3=4(x+1)

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.
