Given:
A table of values of a linear function.
To find:
The slope, y-intercept and equation of the function.
Solution:
Take any two points on the table.
Let the points are (-1, -3) and (0, -6).
Slope of the line:




m = -3
Slope of the function = -3
y-intercept of the function is the point where x = 0.
In the table y = -6 when x = 0
y-intercept = -6
Equation of a line:
y = mx + c
where m is the slope and c is the y-intercept
y = -3x + (-6)
y = -3x - 6
Equation of a function is y = -3x - 6.
Perimeter is the length around an object
Answer:
x = 4
Step-by-step explanation:
3x - 6y = 18
2x + 2y = 6 -> 3(2x + 2y = 6)
3x - 6y = 18 -> Cross out - 6y
6x + 6y = 18 -> Cross out + 6y
9x = 36 -> Divide 9 on both sides.
X = 4
7y - 2y + 8 = 19 + 4y
7y - 2y - 4y = 19 - 8
1y = 19 - 8
1y = 11
Ans is y = 11
