Question

Which test point holds true for 3/2y - 2x>1?


A. (1/4, 1)
B. (4, 1)
C. (1, 1/4)
D. (1, 0)
E. (1/4, 3/4)

Answer 1

Test them, Substitute the first one in. x=1/4 y=1

Answer 2

How do I do that?

Answer 3

\[\frac{ 3 }{ 2 }\times \frac{ 1 }{ 4 }-2\times \frac{ 1 }{ 4 }\]
is it larger than 1

Answer 4

Every point is (x,y)

Answer 5

So substitute the x and y values of each point into your equation.

Answer 6

I got it I multiply 2x by the x values and 3/2 by the y values.

Answer 7

yep, each pair one at a time. then result from the y (3/2) - x result (2x) and see if it is greater than 1

Answer 8

Which inequality is represented by the graph?
A. 7/10x - 2y \[\ge5\]
B. 7x + 10y \[\ge5\]
C. 2x – 7y > 3
D. 10/7 x - 2y <5
E. 10/7 x - 2y \[\le5\]
