Answer:
y = 5/4x -7
Step-by-step explanation:
y = mx + b
parallel line has same slope: 5/4
y = 5/4x + b
(4 , -2) -2 = 5/4 x 4 + b
b = -7
Formula: y = 5/4x -7
Answer:
1.) -4x+30y 2.) distributive property 3.) -4x+30y, (-0.4(3)+3(2)), 10(-1,2)+10(6), -12+60, =48
Step-by-step explanation:
10(-0.4x+3y)= 10(-0.4x)+10(3y)= -4x+30y
10(-0.4(3)+3(2))
10(-0.4(3))+10(3(2))
10(-1.2)+10(6)
-12+60
= 48

If you're looking for the solution to the system of equations, here's how we solve using substitution
We know that y = x - 1, so we can plug that into the first equation giving
2x - 3(x-1) = -1
Now distribute the 3 giving 2x - 3x + 3 = -1. After combining like terms we get -x + 3 = -1. Now subtract 3 from both sides, -x = -4, and multiply both sides by -1 to make x positive. x = 4
Now we can plug that into the second equation to get y
y = x - 1, and we know that x = 4, so y = 4 - 1, y = 3. The solution is (4, 3)
