What are the slope and y-intercept of 5x - 6y + 18 = 0?

Answer and explanation

Correct answer: Slope 5/6, y-intercept 3

The governing idea is that slope and y-intercept are read after writing a linear equation as y = mx + c. Begin with 5x - 6y + 18 = 0. Moving 5x and 18 to the other side gives -6y = -5x - 18. Dividing every term by -6 changes both signs and produces y = (5/6)x + 3. Thus the coefficient of x, the slope m, is 5/6, while the constant term, the y-intercept c, is 3. Therefore option A is correct. Option B incorrectly keeps the negative signs after division by -6. Options C and D confuse the original coefficients with the values obtained in slope-intercept form, so they do not describe the line correctly.
