Question

The equation of line WX is y = −2x − 5. Write an equation of a line perpendicular to line WX in slope-intercept form that contains point (−1, −2)

y = 1 over 2x + 3 over 2

y = negative 1 over 2x + 3 over 2

y = 1 over 2x − 3 over 2

y = − 1 over 2x − 3 over 2

Answer 1

the equation of the line is

y = 1 over 2x − 3 over 2,
for x=-1, y= 1/2(-1)-3/2= -1-3 /2=-4/2=-2.
