Step 1: Find the slope:
To find the slope, find two points on the graph and count the “rise over run” between the points.
Two points here are (0,-1) and (2,1). To get from (0,-1) to the other point, you need to go “up 2” and then “right 2”. This means your slope is 2/2 or 1.
Step 2: Find the y-intercept:
We can see the y-intercept is (0,-1) on the graph. We’ll use the “-1” from that point for our equation.
Step 3: Put it all together:
The slope-intercept form is y=mx+b, where m is the slope and b is from the y-intercept.
Putting Step 1 and Step 2 into play, we have:
y = x - 1
Note: since m=1, we don’t need to write y = 1x -1. That 1 on the 1x is unnecessary.
Answer:
65 pi cm^2
enter 65 in it
Step-by-step explanation:
as l is 13 by Pythagoras
I^68 is the same as i^4
I is the square root of -1
The square root of -1 to the fourth power is 1.
Answer:
y = 2x^2 + 4x - 2
Step-by-step explanation:
y=2(x+1)^(2)-4 is in vertex form. We want the same equation in standard form, which looks like y = ax^2 + bx + c.
Perform the indicated multiplication (squaring of x + 1):
y = 2(x^2 + 2x + 1) - 4, or
y = 2x^2 + 4x + 2 - 4, or
y = 2x^2 + 4x - 2 This is in the standard form of a quadatic.
It contains only one point that is x=6/4 y=-1/2
Hope it helps.
