y = x2 + 8x - 7 a = 1, b = 8, c = -7 the equation of the axis of symmetry: x = -b/2a x = -8/(2*1) = -4
For a quadratic equation y=Ax2+Bx+C, the line of symmetry is given by x=-B/2ASo for the equation y=-x2+x+3, B is 1 and A is -1, so the line of symmetry isx=1/2
The value of m is the slope and the value of b is the y intercept.
The graph of the equation is a straight line. 'm' is its slope. 'b' is its y-intercept
That depends on the values of m and b because it is the formula for a straight line equation whereas m is the slope and b is the y intercept
