Answer:
(- 3, - 6, 0)
Step-by-step explanation:
Since the dilatation is centred at the origin, multiply each of the coordinates by the scale factor 3
(- 1, - 2, 0) → (- 3, - 6, 0)

Answer: 8m+2+4n
Step-by-step explanation:
Since there are no other terms with m or n you subtract 14 and 12 and you keep 8m and 4n. 14-12=2 so the expression is 8m+2+4n
Answer:
y = -3/5x + 3/2
Step-by-step explanation:
begin with the slope-intercept form of a line which is: y = mx + b
'm' is the slope and 'b' is the y-intercept
the y-intercept is given but we need to find the slope
we can do so by using the points created by the x-and-y intercepts:
(0, 3/2) and (5/2, 0)
3/2 ÷ -5/2 = -3/5 (slope)
y = -3/5x + 3/2
