Math Problem Statement
Determine the slope and the y-intercept from the table of values:
x y -2 10 0 6 1 4 3 0 5 -4
slope =
y-intercept =
Solution
To determine the slope and the y-intercept from the table of values, we'll first find the slope , using the formula for the slope between two points:
Let’s use the points and :
So, the slope .
Now, to find the y-intercept, we can use the slope-intercept form of a line . Since we know the slope , we can substitute one of the points from the table (for example, ) into the equation to find the y-intercept .
At , :
Thus, the y-intercept is .
Final Answer:
- Slope =
- Y-intercept =
