Step-by-step explanation:
y = ¼x + 2
m1 = ¼
m of line perpendicular = m2
the formula is : m1×m2 = -1
=> m2 = -1 ÷ m1
= -1 ÷ ¼ = -4
so, the equation is :
y = -4x - 7 (option A)
2x^2+3. the 2x cancel out and the rest is combining like terms
3x-12+5-x=2x-7
2x-7 =2x-7
Means there are infinite solutions.
