Answer:
y = 2x - 8
Step-by-step explanation:
<u><em>To solve for slope, you need to use the formula:</em></u>
m = ![\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
<u><em>Then, plug in the numbers accordingly:</em></u>
m = ![\frac{4 + 2 = 6}{6 - 3 = 3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%20%2B%202%20%3D%206%7D%7B6%20-%203%20%3D%203%7D)
m = ![\frac{6}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B3%7D)
<u><em>Simplify:</em></u>
m = 2
<u><em>Then to find the y-intercept, you take one of the coordinates (doesn't matter which one) and plug it into the equation:</em></u>
Coordinate : (3, -2)
-2 = 2(3) + b
-2 = 6 + b
<u><em>Subtract 6 from both sides:</em></u>
-2 = 6 + b
-6 -6
_________
-8 = b
<u><em>Put it all together:</em></u>
y = 2x - 8

Answer:
1/2
Step-by-step explanation:
2/5 = 4/10
4/10 + 1/10 = 5/10
5/10 = 1/2
Answer:
a. $1000
b. 100
c. 900
d. 1017
Step-by-step explanation:
a.
marked price = 800×1.25=1000
b.
discount amount
1000×0.9=900
1000-900=100
c.
1000×0.9=900
d.
900×1.13=1017
Step-by-step explanation:
If the slope is parallel m1=m2=-3
eqn of line is
y-y1=m(x-x1)
y-2=-3(x-3)
y-2=-3x+9
3x+y=11
