Question

Q4) y=2x+5 is a straight
line passing through the
point (1,5).​

Answer 1

Answer:

no

Step-by-step explanation:

point should not be 1,5

Answer 2

Answer:

Let y=mx+c be the equation then,

we know that when angle between two line is θ, then

tanθ=

1+m

1

m

m

1

−m

tan45°=

1+m⋅2

m−2

⇒m−2=2m+1

⇒m=−3

∴y=−3x+c passes through (1,2)

∴c=2+3=5

∴y+3x=5 is the equation.
