Answer:
i=d ii=c iii=b iv=a
Step-by-step explanation:
You can find slop by doing rise/run Or the increase in y over increase in x
You read the graph left to right just like a sentence so if the line is going down from left to right the slope is negative :)
I think Jackyn is correct because 1/2 is half, which means it is .50. So 1/4 would be much smaller than .50 except if it was 2/4. The bigger the number is in negative, the smaller the number.
Graphing the inequalities
y ≥ 0 are the points above the x-axis including the points along the x-axis
y < x are the points below the line y = x
x + y < 6 are the points below the line x + y = 6
The solution to this is the region bounded by the lines connecting the points
(0, 0)
(0, 6)
(3, 3)
Since it is a right angle triangle
use Pythagoras theorem
20^2 = 3x^2 + 4x^2
400 = 9x^2 + 16x^2
400 = 25x^2
x^2 = 400/25
x^2 = 16
x = 4
