Answer:
range: {15, 11, 7, -3, -7}
Step-by-step explanation:
when x = -4, y = 15
when x = 2, y = 11
when x = 0, y = 7
when x = 5, y = -3
when x = 7, y = -7
Answer:
y = 5x - 2
Step-by-step explanation:
Gradient is also known as slope . The gradient of a line is represented by the equation
Slope (m) = y - y1/ x - x1
Where m = 5 , x1= 1 and y1 = 3
Imputing the values into the equation
m = y - y1/ x - x1
5 = y - 3 /x - 1
Cross multiply, we have
y -3 = 5(x - 1)
Expand
y-3 = 5x - 5
Add 3 to both sides
y-3+3 = 5x - 5 +3
y = 5x - 2

Answer:
Step-by-step explanation:
Simplifying
2x + 13 = 0
Reorder the terms:
13 + 2x = 0
Solving
13 + 2x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-13' to each side of the equation.
13 + -13 + 2x = 0 + -13
Combine like terms: 13 + -13 = 0
0 + 2x = 0 + -13
2x = 0 + -13
Combine like terms: 0 + -13 = -13
2x = -13
Divide each side by '2'.
x = -6.5
Simplifying
x = -6.5
