​

Multiple Choice

what is slope-intercept form?

• A proportional linear relationship

• $$y=mx+b$$ where m=slope and b=y-intercept

• A straight line that goes thru (0,0)

Multiple Choice

Identify the slope and the y-intercept of

$$y=-3x+0.5$$  

• m= 0.5; b=-3

• m=-3x; b= 0.5

• m=-3; b= 0.5

Multiple Choice

• $$y=-6x-\frac{2}{3}$$

• $$y=-\frac{2}{3}x\ +6$$

• $$y=-\frac{2}{3}x-6$$

• $$-\frac{2}{3}x-6$$
