Tanα=opposite/adjacent
tanα=height/distance
tanα=7/16
α=arctan(7/16)°
α≈23.63° (to nearest hundredth of a degree)
First you need to find the slope using y2-y1/x2-x1, which is 7-3/31 you'll get 2 and thats the slope (m).
Next, use the formula: y - y1 = m (x - x1)
Plug in ONE of the points just ONE instead of x1 and y1, (Either one of them it doesnt matter) which is: (using the first point) y - 3 = 2(x - 1) after solving you'll get: y = 2x + 1 which is the answer
Hope this helped!
31 tenths is the answer because 10+10=20+1=31
Answer:
14x+4
Step-by-step explanation:
5x+5x+2x+2x+3+3-1-1
5x+5x+2x+2x=14x
3+3-1-1=4
14x+4
