Answer:
x < -3 1/2 or 3.5
Step-by-step explanation:
-9x + 5 < 17
13x +25 < -1
If we add the 2 equations together, we will have
4x + 30 < 16
4x < 16 - 30
4x < -14
Divide both sides by 4
x< -14/4
x < -3 1/2 or 3.5

Answer:
y - intercept = 0
Slope of line = 2.86
Step-by-step explanation:
THE y-intercept is the point on the y - axis where the line crosses the y - axis. The y-intercept of the graph is 0.
The slope of the line is the ratio of change in the y-axis to the x - axis.
Gradient / slope = Δy / Δx = (y2 - y1) / (x2 - x1)
Drawing a right angle triangle at any point on to meet the line of best fit :
y2 = 35, y1 = 15, x2 = 12, x1 = 5
Slope = (y2 - y1) / (x2 - x1) = (35 - 15) / (12 - 5)
Slope = 20 / 7 = 2.857
Slope = 2.86
