Answer:
a is 2.5
b is 1
gradient is rise over run
• Expand (2a + b)²:
(2a + b)²
= (2a + b) · (2a + b)
Multiply out the brackets by applying the distributive property of multiplication:
= (2a + b) · 2a + (2a + b) · b
= 2a · 2a + b · 2a + 2a · b + b · b
= 2²a² + 2ab + 2ab + b²
Now, group like terms together, and you get
= 2²a² + 4ab + b²
= 4a² + 4ab + b² <——— expanded form (this is the answer).
I hope this helps. =)

Answer:
Slope Intercept Form: y=3x+10
Slope: 3
y: 10
Step-by-step explanation:
y-3x=10 Add 3x to both sides. The y has to be isolated.
So it is y=10+3x So we have to reorder it so y=3x+10
