<u>Answer-</u>
<em>The </em><em>first graph</em><em> represents </em>
<u>Solution-</u>
The given function is,
Putting x = 1,
So, the point (x, f(x)) i.e (1, 6) must satisfy or lie on the curve of the function.
Only in case of the first graph, the point (1, 6) lies on the curve.
Therefore, the first graph represents the function correctly.
Answer:
y = 2x + 8
Step-by-step explanation:
Find the slope of a line between (-8,-8) and (-9,-10) using m = , which is the change in y over the change in x.
Substitute in the values of x and y into the equation to find slope.
Simplify.
Simplify the numerator.
Multiply -1 by -8
Add -10 and 8
Simplify the denominator.
Multiply -1 by -8
Add -9 and 8.
Divide -2 by -1.
Using the point slope form plug in m = 2,
Solve for y.
Multiply -1 by -8
y + 8 = ( 2 ) ( x − ( − 8 ) )
Simplify ( 2 ) ( x − ( − 8 ) ) .
Multiply − 1 by − 8
y+8 = 2 ( x + 8 )
Apply the distributive property.
y + 8 = 2 x + 2 ⋅ 8
Multiply 2 by 8 .
y + 8 = 2x + 16
Move all terms not containing y to the right side of the equation.
Subtract 8 from both sides of the equation.
y = 2 x + 16 − 8
Subtract 8 from 16 .
y = 2 x + 8
