Q: The slope of the line 3/7(x + 1) = 4/7(y - 1) is
UNANSWERED.
The correct answer is C.
A: The answer is 3/4. First solve for y. 3/7(x + 1) = 4/7(y - 1) 3(x + 1) = 4(y - 1) 3x + 3 = 4y - 4 4y - 4 = 3x + 3 4y = 3x + 7 y = 3/4x + 7/4 The line is now in the y = mx + b format. m is the slope of the line and b is the y-intercept. m is 3/4, so that's the slope of the line.
