Math Problem Statement

What is the slope of the line that passes through the points (0, -2) and (4, 1)?

Solution

The problem asks to determine the slope of the line that passes through two points: (0,2)(0, -2) and (4,1)(4, 1).

Formula for the slope:

m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1}

Substituting the given points:

  • (x1,y1)=(0,2)(x_1, y_1) = (0, -2)
  • (x2,y2)=(4,1)(x_2, y_2) = (4, 1)

m=1(2)40=1+24=34m = \frac{1 - (-2)}{4 - 0} = \frac{1 + 2}{4} = \frac{3}{4}

Final Answer:

The slope of the line is 34\frac{3}{4}.

Tip:

When calculating slope, always ensure the denominator (x2x1x_2 - x_1) is not zero to avoid division by zero errors!
