Question

21. Write the equation of a line that is perpendicular to the given line and that passes through the given point.

y - 3 = 8/3(x + 2); (-2, 3)

Answer 1

i think it might be (0,-2)

Answer 2

What is the slope in the first formula?

Answer 3

Basic equation of the line : y=mx+b, where m is a slope
If two lines are perpendicular it means that if one has slope m1 then the other one has m2=-1/m1 (negative reciprocal)
Equation of the line passing through point (x1,y1):
y – y1 = m(x – x1)

1. find the slope of line 2
if line1 y=3x+2 has slope m1=3, then slope of line2



m2=-1/m1=-1/3
2.substitute m2,(x1, y1)=(1,-1)
y-y1=m(x-x1)
y-(-1)=-1/3(x-1)
y+1=-1/3x+1/3
3.write equation in basic form
y=-1/3x-2/3---answer
:D HOPE THIS HELPS!!
