Questions: Graph the equation y = -2x + 5 by plotting point
Transcript text: Graph the equation $y=-2 x+5$ by plotting point
Solution
Solution Steps
Step 1: Identify the equation to be graphed
The given equation is \( y = -2x + 5 \).
Step 2: Determine the range for the plot
To graph the equation, we need to choose a suitable range for \( x \) and \( y \). Let's use the range \( -10 \leq x \leq 10 \) and calculate the corresponding \( y \) values.
Step 3: Calculate the corresponding \( y \) values
For \( x = -10 \):
\[ y = -2(-10) + 5 = 20 + 5 = 25 \]
For \( x = 10 \):
\[ y = -2(10) + 5 = -20 + 5 = -15 \]
Final Answer
The equation \( y = -2x + 5 \) is a straight line with a slope of -2 and a y-intercept of 5.
