Use the point-slope form of a line.
y-yp=m%28x-xp%29
I'll do one, just repeat the steps for the others.
Point:(highlight_green%281%29,highlight_green%282%29)
m=highlight%287%29
y-yp=m%28x-xp%29
y-highlight_green%282%29=highlight%287%29%28x-highlight_green%281%29%29
y-2=7x-7
Standard form means integer coefficients for x and y (multiply both sides by common denominator to get rid of fractions), x and y on the left, constants on the right.
y-2=7x-7
highlight%28-7x%2By=-5%29
