my answer: The line passes through the points (-3, 5) and (2,-5) To find the slope, we find the change in Y divided by change in X. 5 - - 2 / -3 - 2 = 10 / -5 = -2 The slope is -2 Y + 5 / x - 2 = -2 Y+5=-2(x-2) Y+5=-2x+4 Y=-2x-1 Placing the inequality sign, Y< -2x - 1

OpenStudy (alissax):

need my answer checked

OpenStudy (welshfella):

check your last line

OpenStudy (jiteshmeghwal9):

The inequality sign is wrong

OpenStudy (welshfella):

- the inequality sign

OpenStudy (3mar):

It seems you know what you do!

OpenStudy (welshfella):

looks like a typo on your second line - but you got the slope right

OpenStudy (welshfella):

it should be (5 - -5) / ( -3-2)

OpenStudy (jiteshmeghwal9):

The equation of line can be written as Y+2x=-1 Taking any arbitrary point in the shaded region i.e;(2,0). 0+2(2)=4 which is greater than -1

OpenStudy (jiteshmeghwal9):

This implies tht the correct inequality representingthe shaded region is Y greater than -2x-1
