Answer:
Step-by-step explanation:
1) First, find the slope of the equation. Use the slope formula . Substitute the x and y values of the given points into the formula and solve:
Thus, the slope is .
2) Now, use the point-slope formula to write the equation in point-slope form (from there we can convert it to slope-intercept). Substitute values for
,
, and
.
Since represents the slope, substitute
for it. Since
and
represent the x and y values of one point the line intersects, choose any of the given points (it doesn't matter which one, the end result will be the same) and substitute its x and y values into the formula as well. (I chose (4,1), as seen below.) Then, isolate y to put the equation in slope-intercept form and find the answer.
Option c : 9 is the answer.
Explanation:
The expression is
We need to determine the subtracted value of the expression.
From the expression we can see that the expression contains two negative signs.
To simplify the expression, we know that, When we multiply two negative numbers then the product is always positive.
This means
Thus, the expression can be written as
Adding the two numbers, we get,
Thus, the value of the expression is 9.
Hence, Option c is the correct answer.
