To find the rate of change, or slope, pick two points. The slope, is change in y coordinates over change in x coordinates.
slope =  \frac{y2-y1}{x2-x1}.

In this case, the slope is 
\frac{-11+1}{2-0} =  \frac{-10}{2} = -5.
Remember that subtracting a negative number equals adding the number without the negative sign.
a-(-b) = a+b

Now for the y-intercept. The y-intercept is where the graph intersects the y-axis, where x = 0.
You have the coordinate (0, -1), where x = 0. So the y-intercept is -1.

Putting these values into the slope-intercept form y = mx+b, the equation is
y = -5x - 1

IceJOKER [234]

Answer:

Step-by-step explanation:

y=2x²-5x-7

y=2x+2

2x²-5x-7=2x+2

2x²-7x-9=0

2x²-9x+2x-9=0

x(2x-9)+1(2x-9)=0

(2 x-9)(x+1)=0

x=9/2 ,-1

y=11 ,0

solutions are (9/2,11),(-1,0)

Where is 100 degrees celsius located on a thermometer?
luda_lava [24]
Solution 1:
100 degrees Celsius is boiling temperature. The boiling temperature in Fahrenheit is equal to 212, so our answer is 212.

Solution 2:
Let us use the formula for converting Celsius to Fahrenheit. Multiply the number of degrees in Celsius by 1.8 (or 9/5) and add 32. Using this approach, we get to the same answer, 212 degrees.

I hope this will help you!

How would you know the answer (important)
SSSSS [86.1K]

Answer:

okay so I can't see the last option on ur sheet but when u graph this equation the point that lies on the curve is (2,-3) so that is the vertex but if I move up this curved line it passes through the Y axis at (0,-1), the Last answer that I can't see it wouldn't happen to be (-1,6) would it
