Answer:
3
Step-by-step explanation:
slope = (y2-y0)/(x2-x0)
Using pts (-4,-9), (3,12):
(12-(-9))/(3-(-4))= 21/7 = 3
1500m is your answer
As seen from the graph, the curve crosses the x-axis when x = -1 and x = 1. The y-intercept of the curve is -1.
Hence, the quadratic equation of the curve is y = x^2 - 1.

2. 5x > x + 4
4x>4
x>1
3. 3x + 4 < 10
3x<6x<2
4. -10x + 5 -4 > 4x + 3 -1
4x>27
x<1
x<1/7
5. 6x + 3 < 7x - 10
-x<-13
x>13
6. 2x - 4 < 8x + 2
