C(12/15) because the other 3 all equal 0.666666666666667 but 12/15 equals 0.8
3.2-3x+7
6-3x+7
-7 -7
-1= -3x divide both sides by -3
x=0.3
Answer:
y =-2x+7
Step-by-step explanation:
Hello : let A(2,3) B(1,5)
the slope is : (YB - YA)/(XB -XA)
(5-3)/(1-2) = 2/-1 =-2
an equation is : y=ax+b a is a slope
y = -2x +b
the line through point (2,3) : 3 = (-2)(2)+b
b = 7
the equation is : y =-2x+7
