Answer:
He messed up the signs, most likely by multiplying incorrectly. It should be 53x+12.
Step-by-step explanation:
You begin by multiplying both -2 and -10x by -6.
Remember a negative times a negative makes a positive.
-6(-2-10x)
12+60x
Then you need to combine like terms which are 60x and -7x
60x-7x
53x
So that means the final answer will be
53x+12
Answer:
y = x - 3
Step-by-step explanation:
First, you need to find the slope from the two given points.
y2 - y1 / x2 - x1
= 3 - (-1) / 6 - 2
= 1
The slope is 1x or simply x.
For the y-intercept, you need to plug one of the coordinates into the equation, which is y = x + b
3 = 6 + b
-3 = b
So the equation is y = x - 3
Answer:
y=1/2x+1/3
