    4x - 1 = 3y + 5

    slope: 4/3

    y-intercept: - 2

    To find the x-intercept, substitute in 0 for y and solve for x.

    4 x - 1 = 3 (0) + 5

    Solve the equation.

    x = 3 / 2

    To find the y-intercept, substitute in 0 for x and solve for y.

    4 (0) - 1 = 3 y + 5

    Solve the equation.

    Rewrite the equation as 3 y + 5 = 4 (0) - 1.

    3 y + 5 = 4 (0) - 1

    Simplify the right side.

    Multiply 4 by 0.

    3 y + 5 = 0 - 1

    Subtract 1 from 0.

    3 y + 5 = - 1.

    Move all terms not containing y to the right side of the equation.

    Subtract 5 from both sides of the equation.

    3 y = - 5 - 1

    Subtract 1 from - 5.

    3 y = - 6

    Divide each term by 3 and simplify.

    Divide each term in 3 y = - 6 by 3.

    3 y / 3 = - 6 / 3

    Reduce the expression by cancelling the common factors.

    y = - 6 / 3

    Simplify the right side of the equation.

    y = - 2

    These are the x and y intercepts of the equation 4 x - 1 = 3 y + 5.

    x-intercept: (3 / 2, 0)

    y-intercept: (0, - 2)
