Question

What is the intersection point of these two lines
B(t)=20t
W(t) = 10t +30

Answer 1

• The intersection point is (3, 60)

===================

Given

Lines

• B(t)=20t
• W(t) = 10t +30

Find the t-value of intersection by setting right sides equal:

• 20t = 10t + 30
• 10t = 30
• t = 3

Find the y-coordinate of lines:

• B(3) = W(3) = 20*3 = 60
