Step-by-step explanation:
Distribute the -7. -42x + 21.
Answer:
Slope of the line that passes through the points (1, 7) and (3, 3) = -2
Step-by-step explanation:
Given in the question two co-ordinates,
(1, 7)
(3, 3)
here x1 = 1
x2 = 3
y1 = 7
y2 = 3
Formula to use
m = ![\frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D)
= ![\frac{3-7}{3-1}](https://tex.z-dn.net/?f=%5Cfrac%7B3-7%7D%7B3-1%7D)
= -4/2
= -2
The correct answer for the question that is being presented above is this one:
x + y = 5
<span>y = one halfx + 2
</span>y = 1/2 x + 2
-1/2 x + y = 2
Eliminate y by subtracting the two equations.
<span>x + y = 5
</span><span>-1/2 x + y = 2
</span>----------------------
3/2 x = 3
3x = 6
x = 2
x + y = 5
2 + y = 5
y = 5-2
y = 3
So, the answer is (2,3).
It would be 2.1×10 to the power of 13
