Answer:
You plug in numbers into the y=mx+b equation and solve for which ever one you are finding for.
m=slope
x=x intercept
b=y intercept
apply the numbers to this equation and solve or x
Answer: 2cm
Step-by-step explanation:
Answer:
x = 1 and y = 5
Step-by-step explanation:
Use substitution because you know that x = y - 4, and plug this into the first equation to get -10(y - 4) + 3y = 5, or -10y + 40 + 3y = 5. This is -7y = -35 so y = 5. Plug this into the 2nd equation to get that x = 1 and y = 5.
