The equation of a line is y = 2x – 1. What is the equation of the line that is parallel to the first line and passes through (–4, 1)? Anyone help please
OK Do you understand the form of the equation y= mx + b? What is the slope of the line you are given?
is it 2?
yes and all parallel lines have the SAME slope the the line you want to find is y= 2x + b you need to find b but the point (-4,1) is on the line so 1= 2(-4) +b so oyu can find b
So do i just solve for 1=2(-4)+b?
yes- that will give oyu the value of b and you already know that m = 2 fro the line so the answer is y=2x+b
A. y = 2x – 3 B. y = –2x – 7 C. y= -1/2x-1 D. y = 2x + 9
those are the possible answers that i have
OK - so solve the equation for b and you have it
B=-2x+y?
