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).

Answer 1

y=1/2x because the opposite reciprocal of -2 is 1/2. If you insert that into point-slope form, you get y+1=1/2(x+2), which simplifies to y=1/2x.
