Question

PLEASE HELP WILL MEDAL!!

What is the first step of constructing a perpendicular line from a point not on a given line?

Without changing the compass, from each intersecting arc on the line, construct two arcs on the side opposite the given point.

Draw a line from the point to the intersecting arcs.

From the point not on the line stretch the compass and mark two arcs on the line.

Use your ruler and draw a straight line from the point through the line.



Write the equation of a line in slope intercept form that passes through the points (0, 7) and (5, 3)

Answer 1

I believe it is C. From the point not on the line stretch the compass and mark two arcs on the line.

Answer 2

The others do not make sense in terms of the first step.

Answer 3

Thank you so much! Do you know the answer to the second one?

Answer 4

No problem. Slope intercept form is: y=mx+b. With the points of (0, 7) and (5, 3), we need to find the slope so that we can plug the slope into m. Do you know how to find the slope given two points?
