how do you change the equation of 2x+y=-5 into a linear equation and then find the slope and y-intercept?
To change the equation 2x + y = -5 into a linear equation of the form y = mx + b, where m is the slope and b is the y-intercept, follow these steps:
Step 1: Isolate y on one side of the equation.
Start by subtracting 2x from both sides of the equation:
y = -2x - 5
Step 2: Identify the slope and y-intercept.
In the equation y = -2x - 5, the coefficient of x (-2) represents the slope (m), and the constant term (-5) represents the y-intercept (b).
Therefore, the slope (m) of the equation is -2, and the y-intercept (b) is -5.
