Answer:
y = 1/2x -5 slope intercept form
y-1 = 1/2(x-12) point slope form
Step-by-step explanation:
We can find the slope of this line by using
m = (y2-y1/(x2-x1)
= (1--7)/ (12 --4)
= (1+7)/(12+4)
= 8/16
= 1/2
We know the slope and a point, so we can use point slope form
y-y1 = m(x-x1)
y-1 = 1/2(x-12)
y-1 = 1/2 x -6
Add 1 to each side
y-1+1 = 1/2x -6+1
y = 1/2x -5
This is in slope intercept form
Y=Mx+b (m is slope, b is y-intercept)
B because thd mbajdidiidid
