In order to know that a graph shows a proportional relationship WITHOUT finding any y/x ratios or doing division, two conditions must be met. Name ONE of the two ways you know a graph is proportional JUST BY LOOKING AT IT. (You will come across another question that asks you to name the other condition, if you haven't already.) (10 points) please help

I wish I've known, but try using Symbo-Lab or Math-Way. They help a lot.

Step-by-step explanation:

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
