Answer:
1) = H
2) = 0,4
4) = S
Step-by-step explanation:
1) H is found by counting across the horizontal (axis) as x and then downwards the vertical axis for y as y is a negative we find H for y at ( y = -5 )
But when we always read left to right we start with x first at 3 across. (x= 3) as this is the same as (3,-5)
2) We find x, y at (0,4) as 0 is middle of the two axis as they cross each other and 4 goes upwards. x= 0 y =4 = (0,4)
4) S is found as it is a refection of (8,-4) across the y axis.
(x = -8) is still x but it is valued as negative in y as (x = -8)
Then (y = -4) so it stays the same height as y and represents vertical axis line which is called y axis.
And so y reflects the same height.
But in all the others y represents vertical measure generally.
Whilst x represents horizontal measure generally. they both meet at a point which represents two values generally, like cost and time, network output and population, or cupcakes sales and duration/time.
