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

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
