The and would be y=-1/3x-5 because to find slope you would use the equation y2-y1 divided by x2-x1 and find the slope of -4/12 which simplifies to -1/3 and the y-int is -5 so you would just plug that in.
Y=-9/8+7 because you have to find ur slope using rise over run which is -9/8 and you have to find your y intercept which is 7 cause that where it crosses the y axis
