Y=mx+b is equation form.
Step 1: Calculate slope
Slope= y2-y1/x2-x1
Choose 2 points (8,7) and (0,1)
Apply slope formula: 1-7/0-8=-6/-8=3/4(simplified)
M=Slope
Y=3/4x+B
B=Y intercept: 1
Equation: Y=3/4x+1

The complete question in the attached figure
we have that
250°----------> belong to the third quadrant
if 2pi radians-------------> 360°
X-------------------------> 250°
X=250*2pi/360------------> 1.39 pi radians
then
<span>the radian measure of the central angle is 1.39pi
</span>
hence
the answer is
the option C) pi to 1.39pi radians
Answer: 26 years.
Step-by-step explanation:
Let x = current age of Louise (in years).
Then current age of James = x+6
Eight years from now, James's age = x+6+8= x+14
4 years ago, Louise's age = x-4
According to the question
x+14 = 4(x-4)
⇒ x+14 = 4x-16
⇒ 4x-x = 16+14
⇒ 3x = 30
⇒ x= 10 = current age of Louise (in years).
current age of James = 10+6 = 16 years
Sum of current ages = 16+10=26 years.
hence, the sum of the current ages is 26 years.
