What is the equation of the axis of symmetry y equals x2 - 8x plus 16?
y = (x-4)(x-4) * * * The factors above are shown correctly. The axis of symmetry is the vertical line passing through the vertex, which is the point located at (4, 0). The equation of that line is x = 4, which is the answer you requested.
What is y equals 12x plus 120?
It's a linear equation in two variables. When it's graphed, the graph is a straight line with a slope of 12 that intersects the y-axis at y=120.
What is y equals 4x plus 1?
y = 4x + 1 is a straight line making an angle with the x-axis whose tangent is 4 and passes through the point (0,1) or just a line passing though (0,1) and (-1/4, 0)
What is the y intercept of 2x plus 6y equals 36?
A line intercepts the y axis when x=0. If we put x=0 into the equation we get 2x0 + 6y = 36 6y = 36 y = 6 (dividing both sides by 6) Thus the line intercepts the y axis when x is 0 and y is 6. This is the point with the coordinates (0,6)
Which types of lines match these equations x plus y equals 12?
x+y=12 is a linear (straight line) equation in the xy-plane. Alternate forms are y=12-x and x=12-y. The form y=12-x is most familiar, and it is a straight line with a slope of -1 that intercepts the y-axis at 12 and the x-axis at 12.
What is the solution for 3x plus y equals 6?
This is an equation of a straight line. There is no 'one solution' for x and y. The line will cross the y-axis at y = 6, and the slope is -3.
Where does the y equals 4X plus 1 cross the y axis?
when x = -0.25
At which point on the Y axis does the graph line Y equals 3X plus 5 cross A -3 B 3 C 5 D X?
5, of course!
When does the line y equals x plus 2 cross the y axis?
If the equation of the line is written in the standard form: y = mx + c, then it crosses the y-axis at the point (0,c). Here y = x+2 so the y-intercept is (0,2).
Does y equals 3x2 minus 5x plus 1 cross the x axis?
Yes, it crosses at (0.23,0) and (1.43,0).
What is the Graph x plus y equals 3?
It is the line obtained by joining the following points ----->>> (3,0) on x axis and (0,3) on y axis This line is tilted to 45 degrees from negative x axis.
The gradient of the line y equals 4 plus 3 is?
Zero, the line is parallel to the x-axis at a distance 4+3 = 7
How do you graph y plus 7 equals 0?
It is: y = -7 which is a straight line parallel to the x axis
How do you graph y equals negative four plus one?
It is a horizontal line, three units below the x-axis.
Where does y-3x plus 3 equals 0 cross the x axis?
rearrange: y = 3x - 3, which crosses the x-axis when y = 0, ie when x = 1
How many times will the graph of y equals x2 plus 6x plus 9 cross the x axis?
None, it touches it at x = -3.For a quadratic y = ax2 + bx + c, it will meet the x-axis (y = 0) either 0, 1 or 2 times dependent on: b2 - 4ac. If b2 - 4ac is:> 0 the line meets the x-axis twice, so crosses it twice= 0 the line meets the x-axis once, so it does not cross it but only meets it.< 0 the line does not meet the x-axis at all, so cannot cross it.for y = x2 + 6x + 9:b2 - 4ac = 62 - 4 x 1 x 9= 36 - 36= 0so the line meets the x-axis once, but does not cross it - all the values of y are greater than, or equal to zero, but never negative.
What is an equation of the axis of symmetry of the parabola represented by y equals -x2 plus 6x-4?
Line of symmetry: x = 3
