Question

Write the equation of the line that is perpendicular to the line y=2x+2 the and passes through the point (6,3)

Answer 1

perpendicular lines have opposite reciprocal slopes.

y = 2x + 2 what slope does this line have?

Answer 2

y = mx + b , the m is the slope
y = 2x + 2 , the slope is 2

now to find the equation of a line, we need a slope and a y intercept
the perpendicular line will have a slope that is opposite and reciprocal to 2

2 opposite is -2, reciprocal would be -1/2

you with me?

Answer 3

yeah i get it thanx (;
