Since you're doing graphs of linear equations, then you should know by now that
your equation is in a standard form, and you can read straight out of it everything
you need in order to draw the graph.
y = 2x - 2
In this form, the coefficient of 'x' is the slope of the graph, and the constant at the end
is the y-intercept of the graph.
So you can look at it and know immediately the the graph is a straight line,
it has a slope of 2, and it goes through the point [ y = -2 ] on the y-axis.

What is the vertex of the parabola y-2x2-4x 4?
Assuming the missing symbol there is an equals sign, then we have: y - 2x2 - 4x = 4 We can find it's vertex very easily by solving for y, and finding where it's derivative equals zero: y = 2x2 + 4x + 4 y' = 4x + 4 0 = 4x + 4 x = -1 So the vertex occurs Where x = -1. Now we can plug that back into the original equation to find y: y = 2x2 + 4x + 4 y = 2 - 4 + 4 y = 2 So the vertex is at the point (-1, 2)
What describes the translation of the graph of y equals x2 to obtain the graph of y equals -x2 - 3?
No translation will invert a quadratic graph.
Which equation has the steepest graph y equals 7x plus 3 y equals -2x plus 6 y equals -10x - 4 y equals 8x - 1?
y=-10x-4
How do you find the horizontal asymptote of a logarithmic function where x equals 7.5 and y equals 50?
One point on a logarithmic graph is not sufficient to determine its parameters. It is, therefore, impossible to answer the question.
Find an equation of variation where y varies directly as x and y equals 2 when x equals 10 find y when x equals -25?
y = -5
How many times does the graph of y equals 2x2-2x 3 intersect the x-axis?

What is the y-intercept of the graph of y -2x2-4x-3?
-3
Is y equals 2x2 a function?
no
Find the y-intercept of the graph y equals sin x?
It is zero.
What is the graph of the equation 2x2-6x plus 2y plus 18 equals 0?
2x2-6x+2y+18 = 0. Subtract the 2y from both sides. 2x2-6x+18 = -2y. Divide all by -2 to get y by itself. -x2+3x-9 = y. This graph is going to be a parabola that opens downward, like a frown.
Manuel says that the graph of 3y-36 equals 2x2-18x is an ellipse with its major axis parallel to the y-axis Shanice disagrees Who is correct?
3y - 37 = 2x2 - 18x3y = 2x2 - 18x + 37y = (2/3)x2 - 6x + (37/3)The graph is a parabola.Shanice outshines Manuel.
Find the constant of variation and the slope of the given line from the graph of y equals 2.5x?
find the constant of variation and the slope of the given line from the graph of y=2.5x

What is the vertex of the graph y-2x2 8x-3?
y=-2x^2+8x+3
What describes the translation of the graph of y equals x2 to obtain the graph of y equals -x2 - 3?
No translation will invert a quadratic graph.
Is y equals 3x plus 1 and -2x2 a function?
No.
Tell whether the graph opens up or down Find the coordinates of the vertex Write an equation of the axis of symmetry for the equation y equals 2x2 plus 3x plus 6?
y = 2x2 + 3x + 6 Since a > 0 (a = 2, b = 3, c = 6) the graph opens upward. The coordinates of the vertex are (-b/2a, f(-b/2a)) = (- 0.75, 4.875). The equation of the axis of symmetry is x = -0.75.
