Answer:

y = 1.50x +2

Explanation:

First, we must find two points.

  • (0, 2) --- > y-intercept
  • (1, 0.5)

Equation of a straight line:

y = mx + b ------(i)

Step 1: Calculating Slope (m).


m=(y_2-y_1)/(x_2-x_1)


m=(2-0.500)/(1-0)


m=(1.50)/(1)


m=1.50

Now putting value of m in equation (i)

y = 1.50x + b -----(ii)

Step 2: Calculating Y-intercept (b).

Lets choose the first point, (0,2) for calculating y-intercept:

  • y = mx + b

2 = 1.50(0) + b

2 = 0 + b

2 = b

b = 2

Now putting value of b in equation (ii)

y = 1.50x + 2
