Left equatoin seems to be x is less than or equal to -1 the slope seems to be 2 and y intercep tis -1 so 2x-1
right equation is x is greater than or equal to 1 slope is 1 and y intercept is 4 so x+4
top left blank is x+4, top right blank is x is greater than or equal to 1 bottom left blank is 2x-1, bottom right blank is x is less than or equal to -1
Use the slope formula y2-y1 m=--------- x2-x1 (rise-->y over run-->x) so it would be 9-5 m=------- 1-10 and that would simplify to 4 ---- -9 and that would be your slope.
