Answer:
Tell whether the following equations represent a linear function.
<em><u>10x + 2y = 4--linear </u></em><em><u>equation✓</u></em>
−x² + 3y = 19--quadratic equation
<em><u>6x + 1/2y = 3--linear </u></em><em><u>equation✓</u></em>
Y=Mx+B -> slope intercept form
The answer would be -3y=-5x-9
Divide the -3 on both sides and you get
y=5/3x+3
Answer:
y = -4/5x + 14/5
Step-by-step explanation:
Point (6,-2) and (-4,6)
Slope = (6- - 2) / (-4-6) = 8 / -10 = - 4/5
(The slope is negative because La línea is going downhill. Uphill is positive)
You can also find the slope in the graph: rise/run.
y-intersect (any point)
Point (6, -2) (any point)
y-Intercept: -2 - (-4/5)(6) = -2 + 24/5 = 14/5
Hello!
We can go through the choices and see if they are true
Choice 1
A function has one output for every input
This is not a function because it has -1 as an output for both 4 and -1
This is the answer
------------------------------------------------------------------------------------------------------
Choice 2
The inputs are the x's
We see that the inputs are -1, 0, 3, and 4
This is true
------------------------------------------------------------------------------------------------------
Choice 3
The outputs are the y's
We see the outputs are -2, -1, and 1
This is true
------------------------------------------------------------------------------------------------------
Choice 4
We can follow the lines and see the relations are
(-1, 1), (0, -2), (3, 1), (4, -1)
This is also true
------------------------------------------------------------------------------------------------------
The only one that was false was the first choice so that is the answer
The answer is A) The diagram represents a function
------------------------------------------------------------------------------------------------------
Hope this helps!
