<u>Given</u>:
Given that the graph of the linear equation.
We need to determine the equation of the graph.
<u>Slope</u>:
The slope of the equation can be determined using the formula,
Let us substitute the coordinates (2,0) and (0,-4) in the above formula, we get;
Thus, the slope of the equation is 2.
<u>y - intercept:</u>
The y - intercept of the equation is the value of y when x = 0.
Hence, from the graph, it is obvious that when x = 0, the value of y is -4.
Therefore, the value of the y - intercept is b = -4.
<u>Equation of the line:</u>
The equation of the line can be determined using the formula,
Substituting the values, we have;
Subtracting both sides by 2x, we have;
Dividing both sides by -1, we get;
Thus, the equation of the line is
Hence, Option B is the correct answer.
Answer:
slope = if it were in an
Step-by-step explanation:
the graph is a negative and will therefore have a negative slope. to find the slope, pick a point on the graph and find the .
for instance, start with the point (0,1). Then go down 1 and left 2 to get to the next point on the graph (2,0). 1 is the "rise" and 2 is the "run" hence -1/2 being the slope.
you could also use the slope formula:
point 1: (0,1) (x₁ ,y₁)
point 2: (2,0) (x₂ , y₂)
