In function main declare coordinates for two points (x1, y1, x2, y2) and slope m and y-intercept b. call a function get2points to read in the two sets of coordinates. return the values to function main, pass by address(i. e. use pointers to send all four values back to main). call a second function slope intercept to calculate the values of slope m and intercept b for the form y=mx+b. function slope intercept has six parameters, the four coordinate values and pointers to the slope and y-intercept. slope intercept should return slope and y-intercept to main using pointers. from main, print the final form of the equation. the function should not return any value to main using a return statement.

enclose the call statements in a while or loop so that additional coordinates can be converted to the slope intercept format if desired. (ask the user to enter a y if they want to enter more coordinate pairs)
test with coordinate pairs: (4,3) and (-2,1)
(1.1) and (5,17.8)
