The slope-intercept form is y = mx + b.
First find the slope.
m = (y1-y2)/(x1-x2)
m = (-2-5)/(-4-1)
m = -7/-5
m = 7/5
looking for b.
y = mx+b
5 = (7/5)(1) + b
5 = (7+5b)/5
25 = 7+5b
18 = 5b
b = 18/5
so the slope-intercept equation is
y = (7/5)x + (18/5)
12 = 12/1 = 24/2, 24/2+1/2=25/2 so 25/2, and it's in simplest form because 2 can't go into 25
1/4 x 4/7
do the top numbers first. 1 x 4 is 4do bottom numbers next 4 x 7 is 28
that leaves you with 4/28. But you have to reduce.
4/28 = 2/14 = 1/7 (notice I just cut both the top and bottom numbers in half each time I reduced until I couldn't reduce any more).
So, final answer is 1/7
i cant see the question :)
Answer:
D.
Step-by-step explanation:
Find the slope.
Then the y int is 1
It also says less than or equal to
so you shade under
