Question

Write the slope-intercept form of the line with a slope of 2/3 and which contains the

point (9,4)
Select one:
o a. y=-2x + 2/3
o b. y= 2/3x -2
o c. y=2/3x + 10
o d. y= 2/3x + 19/3

Answer 1

The desired equation is y = (2/3)x - 2.

Explanation:

Standard point-slope form is y = mx + b. We have the slope (m) and a point (9, 4) and now must find the y-intercept, b.

y = mx + b becomes 4 = (2/3)(9) + b, or 4 = 6 + b. Then b = -6 + 4, or b = -2.

The desired equation is y = (2/3)x - 2.
