The slope of line D is also -4 because the lines are perpendicular.
Ok ,try putting in 4.15 x 10<span>^-6</span>
You add all those number together then divide the number you got by how many numbers there are and that's your answer, 61.1
edit : dont listen to me I didnt see the numbers 64 and 65, im sorry
2.836x10^-5 is going to be your answer
Slope is -1
Y intercept 3
X Intercept 4
Sorry I do t know the others
Haven’t gone over that
Hope this helps
