Angle M has a measure of 47°. Triangle L M N is cut by perpendicular bisector N P. The lengths of sides L N and N M are congruent. Line segments L P and P M are congruent. Angle P M N is 47 degrees. What is the measure of angle PNL? 43° 47° 86° 94°

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
