Question

Determine the slope (m) and y-intercept (b) of the line:y = 2x - 3A) m = 3, b = 2B) m = 2, b = -3C) m = -3, b = 2D) m = 2, b = 3

Answer 1

slope of line(m) = 2 and intercept on y axis is -2 that is 2 unit in negative y axis.

Equation of line in slope intercept form:

Slope:

            Slope is known as tangent of an angle made by positive X-axis.

                                                                     We know equation of line in slope and intercept form is,

                                               y = mx + b

where,

                       m is slope of line

                       b is intercept on y axis

hence for the given equation,

                                                   y =2x - 3

slope (m) will be = 2

intercept on y axis (b) = -3

thus,

        option (B) will be correct.
