(2x^2-x^2)= x^2
(1+7) = 8
X^2 + 8
I think its the promise to not share it with anyone idk
C would be the correct answer. You caanot multiply just one part of an equation, you must multiply the whole thing. All of the other steps follow this rule, so C is an incorrect step, and is therefore the correct choice.
Hope this helps!
I think it is b that is the answer
Answer:
The equation of the line is:

Step-by-step explanation:
Given the points
Finding the slope between the points




We know the slope-intercept form of the line equation

where m is the slope and b is the slope-intercept form
substituting the value m=2 and the point (-2, -5) to find the b-intercept

-5 = 2(-2) + b
b = -5+4
b = -1
Now, substituting m=2 and b=-1 in the slope-intercept form to get the equation of a line
y=mx+b
y=2x+(-1)
y=2x-1
Thus, the equation of the line is:
