Answer:
The<u> rise divided by the run </u>is the slope of a line. The rise and run are used to estimate the slope of a line from its graph.
To determine the intercepts from a graph, We <u>put y equal to zero</u> and solve for x to find the x-intercept. Similarly, we put x equal to zero and solve for y to find the y-intercept.
A quadratic equation is one in which the highest exponent of x is 2.
is quadratic; the highest exponent is 2.
x³-3x²+1=0 is NOT quadratic. The highest exponent of x is 3, not 2.
