Answer:

y = -5x + 3

y = 7x + 26

Explanation:

Question 1

Given:

  • Slope (m) = -5
  • Point (x₁, y₁) = (5, -22)

Substitute these values into the point-slope formula: y - y₁ = m(x - x₁)

⇒ y - (-22) = -5(x - 5)

⇒ y + 22 = -5x + 25

⇒ y = -5x + 3

Question 2

Given:

  • Point (-4, -2) ⇒ (x₁, y₁)
  • Point (-3, 5) ⇒ (x₂, y₂)

Use the slope formula to find the slope:


\sf \textsf{slope}\:(m)=(y_2-y_1)/(x_2-x_1)=(5-(-2))/(-2-(-4))=7

Substitute these values into the point-slope formula: y - y₁ = m(x - x₁)

⇒ y - (-2) = 7(x - (-4))

⇒ y + 2 = 7(x + 4)

⇒ y + 2 = 7x + 28

⇒ y = 7x + 26
