  1. Write the equation of each line described below. Homework Help ✎

    1. A line with a slope of –2 and y-intercept (0, 7).

    2. A line with a slope of – and x-intercept (4, 0).

    3. A line perpendicular to the line in part (b) with x-intercept (4, 0).

Remember that Slope-Intercept form is y = mx + b.

Substitute 4 for x and 0 for y.

0 = −6 + b

Solve for b.

b = 6
