what is the y-intercept of the line that contains the point ( 3,-2) and is perpendicular to the line y= -2/5x +3/5

Respuesta :

pependicular has slope that multipes to -1

-2/5 times what=-1
5/2

y-y1=m(x-x1)
a point is (x1,y1) and slope is m

y-(-2)=5/2(x-3)
y+2=5/2(x-3)
y intercept
where x=0
y+2=5/2(0-3)
y+2=5/2(-3)
y+2=-15/2
y=-15/2-4/2
y=-19/2
y intercept is at y=-19/2
