Question

Select the equation of a line that is perpendicular to the line on the graph and passes through the point (-1, 2).

Answer 1

any other data given?

Answer 2

y = 2x + 4

y = - 2x + 2

y = - 1 over 2 x + 2

y = 2x - 1

Answer 3

since you have the line with points (0, -1) and (-2, 0)
then we can solve for the slope of the line
Formula would be:
\[m = \frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]
substitute the formula using the points to get the slope

Answer 4

ok thanks
