Question

Which of the following equations defines a line that passes through the point (8,2) and is perpendicular to the line y= -2x + 4?

Answer 1

Answer:b

Explanation:

I plugged all of these into a graph and the used the graph trace feature (after setting the step to 1) and traced all of the graphs to find if they hit the point (8,2). B-d do so we can eliminate a and then you can either graph the line y=-2x+4 or just go with b because they have the same slope (-2x). Hope that helps!
