Question

Select the appropriate linear equation for the trend line.

Answer 1

Answer:

A. y = x + 1

Step-by-step explanation:

Line is passing through the points (0, 1) & (2, 3)

slope of line (m) =(3 - 1)/(2 - 0) = 2/2 = 1

y- intercept (b) = 1 [since y -coordinate in (0, 1) is 1]

Equation of line slope-intercept form is given as:

y = mx + b

plugging the values of m and b in the above equation, we find:

y = (1)x + 1

y = x + 1

Answer 2

Answer:

A y = x + 1

Step-by-step explanation:

The line starts at 1 on the y-axis so the u intercept will be 1
