Answer:
y+5 = -3(x-1) point slope form
y = -3x-2 slope intercept form
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/ (x2-x1)
m = (7--5)/(-3-1)
= (7+5)/(-3-1)
= 12/-4
= -3
The slope is -3
Then we can use point slope form to write an equation
y-y1 = m(x-x1)
y--5 = -3(x-1)
y+5 = -3(x-1)
This is in point slope form
Distribute
y+5 = -3x+3
Subtract 5 from each side
y+5-5 = -3x +3-5
y = -3x-2
This is in slope intercept form
Answer: inverse
Step-by-step explanation: inverse is the relationship between the variables in the table a direct variation.
Answer:
Step-by-step explanation:
line perpendicular to ax+by=c is
bx-ay=k, where k is a constant.
if it passes through (-1,2) then
b(-1)-a(2)=k
or k=b-2a
so reqd. eq . is bx-ay=b-2a
Step-by-step explanation:
You can use the Pick's theorem:

where
<em>i</em><em> - number of lattice points in the interior located in the polygon</em>
<em>b</em><em> - number of lattice points on the boundary placed on the polygon's perimeter</em>
