Slope is used for which of the following situations? Slope is used to determine if lines are parallel. Slope is used to determine if lines intersect. Slope is used to see if points are collinear. Slope is used to find the equation of a line.

the last option

Step-by-step explanation:

All of them

Step-by-step explanation:

By knowing the slope of two lines, we can determine if they are parallel or intersect somehow.  Furthermore, with the help of slope, we can write the equation of a line.  Lastly, you will use slope to determine if several points on a line are collinear.

Hope it helps.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
