The slope (or average rate of change) formula is:
. It is easy to remember as "slope is easy and fun, rise over run" where the y-values of the 2 points would be the "rise" and the x-values of the 2 points would be the "run" So with two points, you label one point as
and the other as
. Then you insert these points into the slope formula (m represents slope). So,
where (-3,6) is x2 and y2 and (5,1) is x1 and y1. It would simplify to
.
Answer:
2 miles per hour
Step-by-step explanation:
1/2×4=2
ratio should be 2miles : 1 hour
From the diagram, ΔRST, ΔRUS and ΔSUT are right triangles. This means that the corresponding legs of the three triangles are proportional, then we can say that the triangles are similar by side-angle-side similarity.
RS/RU=RU/SU
In the figure we can also notice that the acute angles of the corresponding angles are similar, then by angle-angle similarity the triangles are similar.
∠TRS~∠URS~TSU
This implies that: ΔSUT~ΔSRU~ΔRTS
2pi rad=360 deg
so use ratio
(pi/12)/(2pi)=xdeg/360
(pi/24pi)=x/360
1/24=x/360
times boths ides y 360
360/24=x
15=x
the refernc angle is 15 degres
