Aline passes through (–7, –5) and (–5, 4).write an equation for the line in point-slope form. rewrite the equation in standard form using integers.
a) y + 5 = 9/2x – 7); –9x + 2y = 53
b) y + 5 = 9/2(x + 7); –9x + 2y = 53
c) y – 5 = 9/2(x + 7); –9x + 2y = –53
d)y + 7 = 9/2(x + 5); –9x + 2y = 31

Option B is correct.

Step-by-step explanation:

We have been given the points (-7,-5) and (-5,4)

We have an equation for point-slope form:

Here,

On substituting the values in the formula:

Therefore, Option B is correct.

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
