write an equation in slope-intercept form for a line that is perpendicular to the given line and that passes through the given point
the problems are (-10,3); y= -2x-8 (12,8);y=-3x-9 (-1,7);y=-1/4x+6 (4,-9);-x + 2y=10 (2,1);-2x +3y=-12 (-2,3);y=-5x +1
refresh my memory what is the slope-intercept formula?
y-mx+b
y=mx+b*
you know what all the positions are so to find slope u need another point so i am only going to explain ONE and u will do the rest ok?
ok
(-10,3); y= -2x-8 sub in the -10 for the x position wat do ya get?? when you solve it
you get y=20-8...y=12
so now u have your other point and u take (-10,12) and put it in the slope formula to find the slope.. y2 - y1 divided by x2 -x1 so do that
i don't get that part
can you like do the next problem with steps and i will do the other ones by looking at your steps
oh sorry i have to go i cant
:( ok
To make a perpendicular line, you just take the negative reciprocals of the slope
