Writing Explain how you can use an equation to make predictions about a particular relationship​
tresset_1 [31]

Answer:

the intercept of the line with the y-axis. Substitute the line's slope and intercept as "m" and "c" in the equation "y = mx + c." With this example, this produces the equation "y = 0.667x + 10.33." This equation predicts the y-value of any point on the plot from its x-value.

Please help me :'( I have been stuck on this
madam [21]

This is really weird.

-- NONE of the situations matches the equation at the top. 

-- And the equation at the top isn't even really any big deal . . .
it's <em>always</em> true, no matter what  ' t '  is .  If you remove all of
the parentheses and simplify it, it says that  6 = 6.  Well duh !

Please help I am terrible at algebra
Marina CMI [18]

Answer:

y = (x-0)^2 + (-5)  ⇒ y = x^2 - 5

Step-by-step explanation:

The general vertex form of the parabola  y = a(x - h)² + k

Where (h,k) is the coordinates of the vertex.

As shown at the graph the vertex of the parabola is the point (0, -5)

So,

y = a(x-0) + (-5)

y = ax^2 - 5

To find substitute with another point from the graph like (1,-4)

So, at x = 1 ⇒ y = -4

-4 = a * 1^2 - 5

a = -4 + 5 = 1

<u>So, the equation of the given parabola is ⇒ y = x^2 - 5</u>
