Question

Which is an equation of the line through the origin and (7.2)? ​

Answer 1

Answer:

y = 2/7x

Step-by-step explanation:

Step 1 = Slope Formula        y2-y1 / x2-x1  = slope(m)                                        Two points (x y) (x y) = (origin) (given) = (0,0) and (7,2)  

slope (m) = 2-0 / 7-0 = 2/7

Step 2   = Point slope formula

y-y1 =m (x- x1)      y1 = 0  and x1 =0 and m = 2/7

y-0= m (x -0)  

y-0=2/7x - 0                                                                                                               y = 2/7x
