Hello!
To do this you will pick an x value, multiply it by the slope and add the y- intercept. Let's try 0.
y=4(0)-1
y=-1
So here, an ordered pair could be (0,-1)
We can try this again for different x-values.
y=4(1)-1
y=3
This gives us the ordered pair (1,3)
y=4(100)-1
y=399
This would give us the ordered pair (100,399)
I hope this helps!

Answer:
$1.50
Step-by-step explanation:
15*.10=1.50
She took 100, the store has - 100
she went back and bough
70 bucks in stuff, the store has - 70
yes, she took the $100 bill and gave it, got back $30, that means she only kept $30 from the original bill.
the store however, lost the original $100 bill plus the $70 in merchandise, so they have -$170.
Answer:
Prime
Step-by-step explanation:
x² + 20x − 36
You must find a pair of numbers that multiply to give -36 and add to give +20.
The likely candidates are 2 and 18, and they must have opposite signs to give a negative product.
+2 × (-18) = -36; +2 + (-18) = -16
-2 × 18 = -36; -2 + 8 = +16
Neither combination gives +20 as the sum.
The expression can't be factored with rational numbers.
The expression is prime.
