The answer is d.
to find the slope you can do y2-y1/x2-x1
8-(-1)/3-0= 9/3 or 3
you can then put one of the points into the slope intercept form y=mx+b or 8=3(3)+b
you get 8=9+b. you subtract 9 from both sides to get -1=b. y intercept means that the point is (0,-1)
I believe the answer is 38
Two bikers meet at a park at A
<h3>
What is triangle?</h3>
The triangle is geometric shape which includes 3 sides and sum of interior angle should not grater than 180°
Biker A needs to stop at the store that is 12 miles east of the park. Biker B heads southeast at a 61° angle at the same time for 24 miles. Once biker A leaves the store he heads southwest at an angle of 89° for 21 miles.
By following of the above statement the triangle is formed shown in the image attached below.
Thus, without using cosine formula, by drawing the triangle according to
the statement. At point A both the bikers were meet
