"Writing linear equations given the slope and a point"

This was discussed in class, and i got all but 2 or 3 problems done, and then ended up with a stomach bug and missed the Q&A day for the assignment, so i'm asking here. the photobucket links are scans of the graphs, cause i dont know how to describe them, as i barely remember what we're asked of...

Write an equation of the line shown in the graph.

I need 24, and 26. i got the rest...

The answers i already had for this type of problem were in the style of y=1/2x+3/2, and y=3/5x, with #/# being fractions, if it helps any...

thanks in advance.
