Question

Here's a graph of a linear function. Write the equation that describes that function. (If blurry zoom in.)

(Express it in slope-intercept form.)

Answer 1

Y=(1/3) -1

Explanation:

Y is eqaul to 1/3 -1

Answer 2

y = (⅓)x - 1

Explanation:

(3,0) and (0,-1)

In y = mx + c,

c is clearly -1 (y intercept)

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

= (-1-0)/(0-3)

= -1/-3 = ⅓

y = (⅓)x - 1
