To find a linear question, we must have two points on the line and we must know the slope.
Let us choose two points at random:
(-6,12) and (-5,14)
Now let us find the slope of the linear line:
![m = \frac{y2-y1}{x2-x1} =\frac{14-12}{-5--6} = 2](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By2-y1%7D%7Bx2-x1%7D%20%3D%5Cfrac%7B14-12%7D%7B-5--6%7D%20%20%3D%202)
So the slope is 2.
Now let us set up the equation which now requires only one point and the slope
let us use the point (-6,12) and the slope of 2
![y-12 = 2(x+6)\\y = 2x +12 +12\\y= 2x +4](https://tex.z-dn.net/?f=y-12%20%3D%202%28x%2B6%29%5C%5Cy%20%3D%202x%20%2B12%20%2B12%5C%5Cy%3D%202x%20%2B4)
So the linear line is y = 2x + 4.
Hope that helps!
Answer:
y=8
Step-by-step explanation:
We need to find the equation for the line.
The first step is to find the slope
We need 2 points (0,2) (2,3)
slope = (y2-y1)/(x2-x1)
= (3-2)/(2-0)
= 1/2
We know the y intercept ( where it crosses the y axis) at 2
Lets use the slope intercept form of the line
y= mx+b
y = 1/2 x+2
If we want to find the value of y when x =12 , substitute the value of x=12
y =1/2 * 12 +2
y = 6+2
y=8
190-(50+80)t=0
190-130t=0
130t=190
t=19/13 so the trains will remain apart for 19/13 hours.
Since ironman is flying at a constant rate of 150mph he will fly:
150(19/13)≈219.23 miles in that time period while the trains are apart.
X=9
A) 3x-7=34
3x= 34+7
3x= 41
x= 41/3
B) x-9=1
x=1+9
x=10
C) dude what is this
D) 4x+5=41
4x=41-5
4x=36
x=36/4
x=9 YAYY
Hope it helps!
