Whats an equation for the line that passes through the point (0, 3) and is perpendicular to the line y=-x+3

Answer 1

y=x+3 is the equation of a line perpendicular to y=-x+3 that goes through the point (0,3)

perpendicular lines have slopes that are negative inverses

the negative inverse of -1 is +1

the slope is the coefficient of the x term, if the linear equation is solved for y

(0,3) is the y intercept

b=3

general equation is y=mx+b where b= the y intercept and m= the slope

in this problem, b=3 and m=1 for the perpendicular line

y=(1)x +3

or just

y =x +3
