do you know what point-slope form is?
so this should be easy. just substitute the numbers in
give u hard time
tell me what point-slope form is.
tells a difference between two points on a line.
The point-slope form expresses the fact that the difference in the y coordinate between two points on a line (that is, y − y1) is proportional to the difference in the x coordinate (that is, x − x1). The proportionality constant is m (the slope of the line).
it's y - y1 = m(x - x1) idk if that's what you meant...
brb i gotta walk mah dog
im at USA
alright i'm back
so it should be easy. you're just substituting the y in the coordinate for y1, the x in the coordinate for x1, and -4 for m
so the answer is y - y1 = m(x - x1)
no, you didn't substitute
our point is (4,1) so x1 is 4 and y1 is 1
y - y1 = m(x - x1) y – 1 = (-4)(x – 4) y - 1 = -4(x - 4) y - 1 = -4x + 16 y = -4x + 16 + 1 y = -4x + 17
which one is it then?
y = -4x + 17
STEp by STEp y - y1 = m(x - x1) y – 1 = (-4)(x – 4) y - 1 = -4(x - 4) y - 1 = -4x + 16 y = -4x + 16 + 1 y = -4x + 17
i thought the answer was supposed to be in point-slope form
so how can i write y = -4x + 17 to point-slope form
lol. it was already in point-slope in step 1. y - 1 = -4(x - 4)
haha never knew that
