what is the equation of the line in point slope form that has a slope of -7/8, going through point (12,-3)

y= (-7/8)x +7.5

Step-by-step explanation:

We know that the form for the equation of a line is

y= mx+b, with m being the slope, so our equation is

y=(-7/8)x+b. As b should be a constant, we need to find b. Plugging (12,-3) in, we have -3 = (-7/8)(12)+b =  -10.5+b. Adding 10.5 to both sides, we get b= 7.5, making our equation

y= (-7/8)x +7.5

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

the answer

b. they are parallel and will never intersect.
