A student is attempting to find the equation of a line given a point and the slope. Which of the following statements best applies to the sample mathematical work shown below? Given (10, –2) with a slope of –1, I find an equation for the line by plugging in values I'm given into a point-slope form equation. Thus I have y – (–2) = –1( x –10), which results in an equation of y = –x + 8.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

47 - 90 = 43

43 - 180 = x

x = 137

it is x equals 3   plese mark me really need it
