Question

The relationship between the data in the table is linear. Write an equation in slope-intercept form that represents the data in the table

Answer 1

y = -8x +2

Explanation:

The value when x=0 is the y-intercept: b = 2.

The difference in y-values divided by the corresponding difference in x-values is the slope:

m = (y2 -y1)/(x2 -x1)

m = (-6 -2)/(1 -0) = -8 . . . . . using values for x=0 and 1

The slope-intercept form uses these values directly:

y = mx +b . . . . . line with slope m and y-intercept b

y = -8x +2
