Find the slope and -intercept of the line
Find the slope and \( y \) -intercept of the line \( 0.2 x-y=1.2 \)
- A. slope \( =0.2, y \) -intercept \( =-1.2 \)
- B. slope \( =1.2, y \) -intercept \( =-1.2 \)
- C. slope \( =0.2, y \) -intercept \( =-2.2 \)
- D. slope \( =0.2, y \) -intercept \( =-1.3 \)
Step-by-step solution
Start with equation 0.2x - y = 1.2. Solve for y: subtract 0.2x from both sides gives -y = -0.2x + 1.2; multiply by -1 to get y = 0.2x - 1.2. This is in slope-intercept form y = mx + b, where m is slope and b is y-intercept. Thus slope = 0.2 and y-intercept = -1.2.
