Question

Can someone show me how to solve 10 & 12

Answer 1

Given:

Line 1: (-1, 2) and (2, 3)

Line 2: (0, 0) and (3, 1)

We will find the slope of each line

`slope=(rise)/(run)=(y_2-y_1)/(x_2-x_1)`

the slope of line1 = m1

`m_1=(3-2)/(2-(-1))=(1)/(3)`

the slope of the line2 = m2

`m_2=(1-0)/(3-0)=(1)/(3)`

So, the slope of line1 = the slope of line2

So, the lines are parallel
