Write the equation of each line described below. Homework Help ✎
A line with a slope of –2 and y-intercept (0, 7).
A line with a slope of –
and x-intercept (4, 0).
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
