Question

find the slope and y intercept of the line 9x +2y=31

Answer 1

slope is -9/2

Answer 2

Change into Slope-Intercept form.
y = mx + b
m is slope
b is y-intercept

9x + 2y = 31
Subtract 9x.
2y = -9x + 31
Divide both sides by 2.

y = -9/2x + 31/2
or as decimal:
y = -4.5x + 15.5

What's the slope? What's the y-intercept?
