Answer:
Step-by-step explanation:
The first one is in standard form;
the second one is in point-slope form;
the third one is in slope-intercept form;
the last one is in standard form
These are all lines, so as you can see, there are 3 different formats for writing the equation of a line.
y-y1 = m(x-x1)
y-2 = 7(x-1) point slope form
y-2 = 7x-7
add 2
y=7x-5 slope intercept form
