Slope-intercept form of a linear equation:
(where m is the slope and b is the y-intercept)
Maria's line:
Therefore, the slope of Maria's line is
If two lines are perpendicular to each other, the product of their slopes will be -1.
Therefore, the slope of Nate's line (m) is:
Therefore, the linear equation of Nate's line is:
Rearranging this to standard form:
Therefore, <u>option c</u> could be an equation for Nate's line.
