The basic structure of a linear function is y=mx+b (or +c, depending on your schools curriculum)
We need to find the slope (m), and the y-intercept (b/c)
To find the slope you can pick two random points, say (2,2) and (0,1)
The formula for the slope is this: m= y1-y2 / x1-x2
So if we substitute the points in, we get 2-1 / 2-0 = 1/2
Knowing the slope, it can be substituted into to the equation: y=1/2x + b
Then, if you notice the second point- (0,1), it’s the y-intercept. The y coordinate there is 1.
To check if this is correct, a random coordinate set can be picked and substituted in to find b.
y= 1/2x + b
2 = 1/2 *2 + b
2 = 1 + b
2-1=b
1=b
Therefore, the final linear function is y = 1/2 x + 1
Answer:
(-2,0)
Step-by-step explanation:
y=-2x-4
y=x+2
------
- x+2= -2x-4
- 3x=-6
- x=-2
- y=x+2=-2+2=0
(-2, 0) is the answer
Answer:
Y=-4x+8
Step-by-step explanation:
y2-y1/x2-x1
This wil give you slope.
