Answer:
y = -8x -25
Step-by-step explanation:
The 2-point form of the equation of a line is useful when you are given 2 points.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (7 -(-1))/(-4 -(-3))(x -(-3)) +(-1)
y = 8/-1(x +3) -1
y = -8x -25
Answer:
A score of 117 is needed, which Is not possible since the test is over 100.
Step-by-step explanation:
The other 3 scores are 85, 94,84 . Let's x be the 4th score he must score.
Therefore ( 85 + 94 + 84 + X)/4 =95
Then 263+X /4 =95
Cross mutiplying 4*95=263+X
Therefore X= 380-263
X= 117 which is not possible since the test score is over 100.
I think the answer is √20
let me know if I'm wrong. hope this helps
There are two ways to approach this.
Option #1:
Use the slope formula 
.
That value is undefined, so the slope is undefined.
Option #2:
Because the two points have the same x-value, they will be vertically above/below one another. This means your line is a vertical line and the slope of a vertical line is undefined.
Either way, your slope is undefined.
