Question

Paul wants to write equations in the form y=mx + b for the lines passing through

point D that are parallel and perpendicular to line h. First he finds the slopes of these
two lines. What could he do next to find the y-intercepts?

Answer 1

Y is greater then 1

Answer 2

Substitute the slope and the coordinates of point D in the equation of the line y=mx+b and then solve for b in each equation

Explanation:

we know that

The first step is calculate the slopes of these two lines. Remember that if two lines are parallel then the slopes are the same (m1=m2) and if two lines are perpendicular then the slopes is equal to m1*m2=-1

The second step is substitute the slope m2 and the coordinates of point D in the equation of the line in slope-intercept form y=mx+b and then solve for b in each equation
