Answer:
Slope of the line = 1
Step-by-step explanation:
A line with two points, we are asked to find the slope
We are using the formula
m = (y_2 - y_1) /( x_2 - x_1)
We are provided with some points
( -9 , -9) ( -6 , -6)
x_1 = -9
y_1 = -9
x_2 = -6
y_2 = -6
Insert the values into the equation
m = (y_2 - y_1) / (x_2 - x_1)
m = ( -6 - (-9)) / ( -6 - (-9))
Hint: - * - = +
m =( -6 + 9) / ( -6 + 9)
= 3 / 3
= 1
Slope m = 1
Therefore, the slope of the line = 1
Your answer to this question is B
For this case we must indicate an expression equivalent to:
For properties of powers we have to:
So, the above expression can be rewritten as:
Thus, the resulting expression is:
