Answer:
2x-y=4
Step-by-step explanation:
y=mx+b
b is the y-intercept which is -4
y=mx-4
find m(slope)
(2,0) and (0,-4)
(-4-0)/(0-2)
-4/-2=2 m=2
y=2x-4
add 4 to both sides
y+4=2x subtract y
4=2x-y
It says write in standard form which looks like this: 3x + 5y = 4
Answer:
A.
Step-by-step explanation:
The Elimination Method is the method for solving a pair of linear equations which reduces one equation to one that has only a single variable.
If the coefficients of one variable are opposites, you add the equations to eliminate a variable, and then solve.
If the coefficients are not opposites, then we multiply one or both equations by a number to create opposite coefficients, and then add the equations to eliminate a variable and solve.
When multiplying the equation by a coefficient, we multiply both sides of the equation (multiplying both sides of the equation by some nonzero number does not change the solution).
So, option B is not allowed (it is not allowed to multiply only one part of the equation)
