point slope, slope intercept and standard form
point slope: y-y1=m(x-x1), where y1 is point y, x1 is point x, and m is the slope.
First time the slope using (y2-y1)/(x2-x1), for points (x1,y1) and (x2,y2)
First find the slop m. (4-5)/(-3/1) = m = (1/4)
Then pick either point (I will use (5,1)) and plug it into point-intercept form: y-(1)=(1/4)(x-5) and simplify for y
there is only one point intercept form, the equation should be the same for both points since the slope is the same
y-1=(1/4)x-(5/4) +1 +1 y=(1/4)x-(1/4)
@nikato I can't explain well
standard form is in the right form, for point slope you have the right form as well. the point slope form is right as well. i did not calculate any numbers.
@trollface yea, all three are right
