Question

find the equation for the line perpendicular to y=4/3x+1 with y-intercept 0,15 in slope-intercept form

Answer 1

y = (-3/4)x + 15

Explanation:

The slope of the given line is 4/3. The slope of a line perpendicular to this given line is the negative reciprocal of 4/3, which comes out to -3/4.

Now that we have both the slope and y-intercept of the new line, we're ready to write out the desired equation in slope-intercept form:

y = (-3/4)x + 15
