i would probably say the first option. you basically want to use the 2 points that are outside of the majority of all of the other points. in this case, i am pretty sure it would be the first option. i am not 100% sure, but i think that's the correct answer :)
Calculate the square root which is -7*6-(-2)*(-3) and then multiply the numbers which is -42+2*(-3) that equals -42-6 and your answer is -48
Answer:
Step-by-step explanation:
1. The y-values in the table are constant, so the slope is 0. It is a horizontal line.
There is no x-intercept.
The y-intercept is (0, 1).
__
For lines in standard form, the intercepts can be found easily. The x-intercept is the value of x when y=0:
ax +0 = c
x = c/a . . . . x-intercept
Similarly, the y-intercept is the value of y when x=0:
0 +by = c
y = c/b
__
3. x-intercept = (-20/2, 0) = (-10, 0)
y-intercept = (0, -20/-5) = (0, 4)
__
4. x-intercept = (-6/1, 0) = (-6, 0)
y-intercept = (0, -6/-3) = (0, 2)
Plot these points and draw a line through them.
