Answer:It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.
Step-by-step explanation:
The Y intercept of a straight line is simply where the line crosses the Y axis.
Example
Y intercept
In the above diagram the line crosses the Y axis at 1.
The Y intercept is equal to 1 and the point is written as (0,1). Notice that for the y-intercept the x-coordinate of the point is always zero..
Answer:
3.496
Step-by-step explanation:
Multiply these two by getting rid of the decimal:
38 -<em>decimal is moved one place here.</em>
<u>x092</u> -<em>decimal is moved two places here.</em>
3496 -move decimal three places over.
15 divided by 6 2/3 is 2 1/4
Answer:
7
Step-by-step explanation:
can't explain my steps bcuz it was so ez. got it in a second within looking at it.
We have 4(x^2 - 2x + 4) - 7 = 4x^2 - 8x + 16 - 7 = 4x^2 - 8x + 9;
So, 4x^2 - 8x + 9 = <span>ax^2+bx+c
;
The value of b is -8.</span>
