Final answer:
The equation y=3x-2 is written in slope-intercept form. The equation 21-5y-12 is not in slope-intercept form.
Step-by-step explanation:
The equation y=3x-2 is written in slope-intercept form. In slope-intercept form, the equation of a line is written as y = mx + b, where m represents the slope and b represents the y-intercept. The equation y=3x-2 has a slope of 3 and a y-intercept of -2.
On the other hand, the equation 21-5y-12 is not in slope-intercept form, as it does not have y isolated on one side of the equation.
