What is the equation of the line in slope-intercept form?

y = −2x + 8
y = −8x + 2
y = −2x + 16
y = 16x − 2

What is the equation of the line in slopeintercept form y 2x 8 y 8x 2 y 2x 16 y 16x 2 class=

Read off b immediately:  the y-intercept is at (0,16).  What's the slope?  as we move from x=0 to x=8, y decreases from 16 to 0.  Slope = rise / run = -16/8 =-2.

Then the eqn of the line in slope-intercept form is   y = -2x + 16.
