Y=-2x + 2 make a table of values​
butalik [34]

Answer:

Step-by-step explanation:

The negative sign in y = -2x + 2 tells us immediately that the y intercept of the graph of this function is (0, 2).  If we start at (0, 2) and increase x by multiples of 1, y decreases by 2 in each case (the slope of this line is -2).  Thus, we begin a table as follows:

 x   y = -2x + 2

 0   2

 1    -2(1) + 2 = 0

 2   -2(2) + 2 = -4 + 2 = -2

and so on:

 x   y = -2x + 2

 0   2

 1    0

 2  -2

 3   -4

 4    -6

Find the y-intercept of each equation.
iren [92.7K]
A. (0, -10)
b. (0, -13)
c. If you’re providing the equation 2 - -2y = 14 the y-intercept is 6, but if you’re providing the equation 2 - 2y = 14 the y-intercept is -6.

What is the vertex of the graph of #y=x^2+3x-4#?
borishaifa [10]
To find the x value of the vertex we do:

x = \frac{-b}{2a}
if your quadratic function is in the form ax² + bx + c = y

x = \frac{-3}{2(1)}
x = \frac{-3}{2}

Now we plug this x into the equation and solve for y.

y = (\frac{-3}{2}) ^{2} + 3( \frac{-3}{2} ) + 4
y = \frac{9}{4} -  \frac{9}{2} + 4
y = \frac{9}{4} - \frac{18}{4} + 4
y = \frac{-9}{4} + 4
y = \frac{-9}{4} + \frac{16}{4}
y = \frac{7}{4}

Your vertex (if my math is correct) is at ( \frac{-3}{2},  \frac{7}{4} )
