<span>When solving a question like this, with two quantities and their different units (centimetres and millimetres in this case) you can begin by converting the values to the same units. this makes the calculations easier.
15 centimeters to millimeters = 15 x 100 ( because 1 cm has 100mm)

<span>Hello : let
A(-3,7) B(3,3)
the slope is : (YB - YA)/(XB -XA)
(3-7)/(3+3) = -2/3
an equation is : y=ax+b a is a slope</span>
y = (-2/3)x +b
the line through point B (3,3) :
3 = (-2/3)(3)+b<span>
<span>b =5
the equation is : y =(-2/3)x+5</span></span>
