write the equation of the line that passes through (-2,1) and is perpendicular to the line y=1/2x+1
Lines that are perpendicular have opposite slopes from each other. so the slope of the line would be -2/1 or just -2
Because the slope of the line its perpendicular to is 1/2. Change the sign and flip the fraction and its -2/1 or -2
see how i got that?
no
and how who u write that at the end
the line you were given is y=1/2x+1. thats in the form y=mx+b where m = slope. you want to find the line that is perpendicular to that. lines that are perpendicular to each other have opposite slope. opposite of 1/2 is -2/1
Now that we have the slope and the point you were given. we can do point slope form and then simplify to get slope intercept form
