Add the following polynomials, then place the answer in the proper location on the grid. Write answer in descending powers of x
Add: x 5.4x4 + 7x 3 + 8. 9x 3 + 7x2 - 10, and -2x 5 + 7x4 - 3x + 8

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
