Answer:
<u>y = -2x + 7</u>
Explanation:
<em><u>y = mx + b</u></em>
<em><u /></em>
<em>m = slope</em>
<em>b = y-intercept</em>
<em>y = a given y coordinate</em>
<em>x = a corresponding x coordinate</em>
<em />
First, we need to find the slope (m).
1) (4, -1)
2) (2/3)
m = slope = 
= 
= 
= -2
plug in the values to the equation <u>y = mx + b</u>
<u />
-1 = -2(4) + b
-1 = -8 + b
7 = b
now, we can substitute in m and b into the equation y = mx + b
<u><em>y = -2x + 7</em></u>

Answer: There are 28.375 grams in an ounce.
Step-by-step explanation:
Given: Total grams in a pound =454 grams
Total ounces in a pound = 16 ounces
Therefore, 16 ounces = 454 grams
To find grams in an ounce, we need to divide 454 grams by 16, we get
The total grams in an ounce=
∴The total grams in an ounce= 28.375 grams
Hence, there are 28.375 grams in an ounce.
X-4y=-18
an easy way is to solve for oone variable
solve for x
add 4y both sides
x=4y-18
when y=1, x=-16
when y=0, x=-18
when y=2, x=-10
(x,y)
so some orderd pairs are
(-16,1)
(-18,0)
(-10,2)
