Question

Write the slope-intercept form of the equation parallel to y = 7x + 2, which passes through the point (1, -3).
	A.	y = 7x - 10
	B.	y = -1/7 x + 2
	C.	y = 7x - 3
	D.	y = -7x + 10

An equation parallel to y=7x+2 would mean that they have the same slope.  In slope-intercept form of y=mx+b, m is your slope.  We now know that the new equation will also have a slope of 7. Afterwards you can plug in the point (1,-3) as values of the equation y=7x+b to find out b, which is the y- intercept.  
-3=7(1)+b
-3=7+b
b=-10
The final answer is A. 7X-10
