You were given the line y = -3x + 8 (which is in slope-intercept form). The standard equation in "slope-intercept form" is y = mx + b (where m is the slope and b is the y-intercept). Compare the specific equation to the general one. What is the value of the slope, m?

@mathmale so slope = 3?

Not quite \[\large y = mx + b\] Compared to \[\large y = -3x + 8\] If the slope is just 3, what happened to that negative sign out in front?
