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.
