What is the y-intercept of the equation of the line that is perpendicular to the line y = 3/5x + 10 and passes through the point (15, –5)? the equation of the line in slope-intercept form is y = x

y- intercept = 20

y = x + 10 has slope m =

The perpendicular slope = - = - = -

perpendicular equation is y = - x + c

where c is the y-intercept

to find c substitute (15 , -5) into the equation

-5 = - 25 + c ⇒ c = - 5 + 25 = 20

y-intercept of perpendicular line is 20

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
