Answer:
2x+1 (2,7)
Step-by-step explanation:
y=mx+b
Answer:
Step-by-step explanation:
To find out the m(slope) of the equation use the formula:
.
Substitute the values:
Combine the values:
Find the value of the fraction:
M is -3.
The equation so far is
To find the y intercept, substitute one pair of coordinates into the equation and solve for b:
.
We see that b =-17 so the full equation would be:
.
Answer:
=
Step-by-step explanation:
Given
Required
Simplify
Rewrite as
Open the bracket
It passes through the center of the points. (2)
When doing a line of best fit, you want the line to have equal number of points on either side of the line.
One line passes through the points (-2,3) and (0,-3) , it means the y intercept is b=-3
and slope m =
So the equation of line will be
And the inequality should be
Or
And the other line passes through (-2,3) and (0,2)
So the y intercept is b=2
and the slope is
So the equation of line will be
Or
So answer is
