The relationship is linear.
To find the equation for the data, we can use two points (-10, -3) and (3, 4):
slope (m) = (y2 - y1) / (x2 - x1)
slope (m) = (4 - (-3)) / (3 - (-10))
slope (m) = 7 / 13
slope (m) = 7/13
Now we can use the point-slope formula to find the equation of the line:
y - y1 = m(x - x1)
y - (-3) = 7/13(x - (-10))
y + 3 = 7/13(x + 10)
y + 3 = 7/13x + 70/13
y = 7/13x + 70/13 - 39/13
y = 7/13x + 31/13
Therefore, the equation for the data is y = 7/13x + 31/13.
To find the equation for the data, we can use two points (-10, -3) and (3, 4):
slope (m) = (y2 - y1) / (x2 - x1)
slope (m) = (4 - (-3)) / (3 - (-10))
slope (m) = 7 / 13
slope (m) = 7/13
Now we can use the point-slope formula to find the equation of the line:
y - y1 = m(x - x1)
y - (-3) = 7/13(x - (-10))
y + 3 = 7/13(x + 10)
y + 3 = 7/13x + 70/13
y = 7/13x + 70/13 - 39/13
y = 7/13x + 31/13
Therefore, the equation for the data is y = 7/13x + 31/13.
