Which inequality matches the graph?
X, Y graph. X range is negative 10 to 10, and Y range is negative 10 to 10. Dashed line on graph has positive slope and runs through negative 10, negative 9 and negative 1, negative 3 and 8, 3. Above line is shaded.
−2x + 3y > 7
2x − 3y < 7
−3x + 2y ≥ 7
3x − 2y ≤ 7

Best ResponseYou've already chosen the best response.0you can use 2 points (10 , 9) and (1 , 3) to calculate the slope, and use the pointslope form to get your equation for the line

Best ResponseYou've already chosen the best response.0slope = m = (change in y value)/(change in x value) = [3  (9)] / [1  (10)] m = 6/9 = 2/3

Best ResponseYou've already chosen the best response.0Using that slope m=2/3 and any point on the line, (x1,y1)= (1, 3) PointSlope Form: y  y1 = m*(xx1)

Best ResponseYou've already chosen the best response.0y + 3 = (2/3)x + (2/3) y = (2/3)*x  (7/3)

Best ResponseYou've already chosen the best response.0From the graph, it is a dotted line meaning it is > or < not equal to, and shaded above means greater, so y is greater than y > (2/3)*x  (7/3)
