Answer:
y=5
Step-by-step explanation:
If it is perpendicular to the y-axis, that means it is a horizontal line so the slope m=0.
Use the equation
y-y=m(x-x)
y-5=0(x-(-4))
y-5=0
y=5
Answer:
3a + 10 = 52
Step-by-step explanation:
- the coefficient is a numerical constant placed before and mulitplying the variable (3).
- the variable is the unknown value of the equation, generally represented by a letter (a).
- the operator is any symbol that indicates an operation to be performed (+, addition).
- the constant is a fixed numerical value (10).
- the total is the resulting value of the equation (52).
It’s the last one, you can check by plugging in the numbers (x,y) and if it’s the same as the number after the equals sign it’s that one
