You subtract similar numbers or variables. Like you take 7 from both sides in this equation. So subtract like numbers/ variables. Then you divide the rest. For example. 5s=23. You divide both sides by 5 to isolate the variable. Then, you have your answer.
Answer:
b= 2 over 7
Step-by-step explanation:
exact form b= 2 over 7
decimal form b= 0.285714
The gradient of the straight line is -3.
<h3>How to find the gradient of a line?</h3>
The gradient of a straight line is the rate at which the line rises (or falls) vertically for every unit across to the right.
The gradient of a line is the slope of the line.
The gradient of the line is the change in the dependent variable with respect to the change in the independent variable.
Therefore, using (0, 4) and (1, 1) let's find the gradient.
gradient = y₂ - y₁ / x₂ - x₁
x₁ = 0
x₂ = 1
y₁ = 4
y₂ = 1
gradient = 1 - 4 / 1 - 0
gradient = - 3 / 1
gradient = - 3
