Final answer:
The correct statement is y = 3x - 7 has a slope of 3, and y = -2x + 2 has a slope of 2.
Step-by-step explanation:
In the slope-intercept form of a straight line, which is y = mx + b, m represents the slope of the line, and b represents the y-intercept.
Based on this formula, for the first equation, the coefficient of x is 3, which means its slope is 3, and for the second equation, the coefficient of x is -2, indicating that its slope is -2.
Therefore, the correct statement regarding the slopes of the given equations is: y= 3x - 7 has a slope of 3, and y = - 2x + 2 has a slope of -2.
