Question

the line y=mx+8 contain the point (-4,4),calculate the value of m.​

Answer 1

Answer:

m=1

Step-by-step explanation:

applying y=4 and x=-4 in equation,

(4)=m(-4) +8

therefore m = 1

hope it helps:)

Answer 2

Answer:-

Given:

( - 4 , 4) lies on the line y = mx + 8.

Simply substitute

• x = - 4

• y = 4

in the given equation.

⟶ 4 = m( - 4) + 8

⟶ 4 - 8 = - 4m

⟶ - 4/ - 4 = m

⟶ 1 = m

∴ The slope of the line is 1.

Additional Information:-

• Slope of a line (m) = y₂ - y₁ / x₂ - x₁ where (x₁ , y₁) & (x₂ , y₂) lie on the line.

• Equation of a line with slope m is y - y₁ = m(x - x₁).

• Equation of a line in slope intercept form is y = mx + c.

• Equation of a line parallel to x - axis at a distance of k units from it is y = k.

• Equation of a line parallel to y - axis at a distance of k units from it is x = k.
