Hello : let
A(5,22) B(2,13)
the slope is : (YB - YA)/(XB -XA)
(13-22)/(2-5) = -9/-3
an equation is : y=ax+b a is a slope
y = 3x +b
the line through point A (5,22) :
22 = 3(5)+b
b = 7
the equation is : y =3x+7
The answer is 3.25 or 3 1/4
3x1,789=5367. as for y 3 digit number is like multiplying a 4 digit number, it's basically the same thing just one digit more.
Answer: 5 problems correct
Work Shown:
20% of 25 = 0.20*25 = 5
