Y = mx + b
slope(m) = 7
(5,30)...x = 5 and y = 30
now we sub and find b, the y int
30 = 7(5) + b
30 = 35 + b
30 - 35 = b
-5 = b
so ur equation is : y = 7x - 5 <==
Answer:
T=-20
Step-by-step explanation:
first get rid of the 7
1. T/4=-5
then multiply by 4 to isolate T
2. T=-20
Times the price of the model cars to the amount bought.
$15×6= 90.
Lea paid 90 dollars for the model cars.
Now, multiply the price of the paint to the amount bought.
$11×4= 44.
Lea paid 44 dollars for the paint.
Add both together. 90+44= 134.
Therefore, Lea paid $134 for the model cars and paint all together.
hope this helps!
