Answer:
y = 4x + 5
Step-by-step explanation:
y2 - y1/ x2 - x1
1 - (-3) / -1 - (-2)
4
y = 4x + b
13 = 4(2) + b
13 = 8 + b
5 = b
y = 4x + 5
4 1/2 + 8 3/4
4+8 = 12
1/2 + 3/4 = 2/4 + 3/4 = 5/4 = 1 1/4
12 + 1 1/4 = 13 1/4
Answer is C
Answer:
b) Substitute (3x - 5) for y in the second equation.
Step-by-step explanation:
If using the substitution method, then the second choice is the most efficient first step.
<u>What is the substitution method?</u>
The substitution method can be used to solve a system of equations. It is when you isolate any of the variables from one of the equations and then substitute that value into the other equation.
Here, the first equation already has an isolated variable, y. We can then substitute its value into the second equation. Like so:
⇒ 2x + 6y = 20
⇒ 2x + 6(3x - 5) = 20
