Question

This is a practice sheet and i am unsure how to so this question

Answer 1

Slope m= 3, for Line I

Line k is parallel to Line I

Then also

m'= 3

and equation of Line k is

y= 3x + b

Then , rest to find b in this equation

with point (3,10)= (x,y)

b = y - 3x = 10 - 3•3= 10-9=1

b= 1

THEN

Equation for Line k

ANSWER IS

y= 3x + 1.
