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?

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

Step-by-step 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

answer choice B

Step-by-step explanation:

.4 equals 4/10, which simplified is 2/5. hope u found what ur looking for :)
