Equation of line is y=mx + c
where c is y-intercept and m is slope.
Sub (3,1) and slope into equation:
1 = -2(3) + c
1 = -6 + c
c = 7
Thus, equation is y = -2x + 7
Ans is (a)
-2/3x +1/3 +x = 2/5
⇒ 1/3x + 1/3 = 2/5
⇒ 1/3x = 2/5 -1/3
⇒ x/3 = 1/15
⇒ 15x = 3
⇒ x = 3/15
⇒ x = 1/5

Answer:
C. (1, -1)
Step-by-step explanation:
Dilation by a factor of 1/3 multiplies each coordinate value by 1/3.
(x, y) ⇒ (x/3, y/3)
K(3, -3) ⇒ K'(3/3, -3/3) = K'(1, -1)
