<h3>What is the linear relationship?</h3>
  • A statistical word used to express a straight-line relationship between two variables is a linear relationship (or linear association).
  • Graphs and mathematical equations of the form y = mx + b can both be used to represent linear relationships.
  • In everyday life, linear relationships are quite prevalent.

The midpoint of the axis is=

  • 10+24/2
  • 34/2
  • 17

In the intercept form-

  • y= mx+b
  • y= mx+3
  • y= mx +3
  • 10 =m(1) + 3

subtracting 3 from both sides-

  • 7=m
  • Y = 7x+3

Hence, the rate of change is 7ft/yrs.

Let V = (8, -4) and W = (-4,2).
kiruha [24]

The second value in a set of parenthesis is the y value, so B is true.

If you multiplied each value of W by -2, you would get the values for V, so C is also true.

The answer is B and C.
