Answer:
y=3x+5
Step-by-step explanation:
Point slope equation:
y=mx+b
m-slope, b- is y-intercept
equation given 2 points
y-y1 = m(x-x1)
For point (1,8) and slope m=(y2-y1)/(x2-x1) = 20-8/5-1=12/4=3
y-8 =3(x-1)
arange it in point slope format
y-8=3x-3
y=3x-3+8
y=3x+5

* represents a multiplication symbol
Answer:
11.1%
Step-by-step explanation:
17/153= 0.111 x 100= 11.1%
Answer:
You can use Gaussian Elimination.
Double both sides of the first equation and add the second equation.
6x + 4y = 8
5x - 4y = 3
---------------
11x = 11
x = 1
5 - 4y = 3
-4y = -2
y = 1/2
