Answer :
y=mx+b
y=7 m=-5/4 x=-4 b=?
7=-5/4(-4)+b
7=5+b
7-5=5-5+b
b=2
Therefore, the equation is y=-5/4x+2
That's it.
y - y₁ = m(x - x₁)
y - 7 = -1¹/₄(x - (-4))
y - 7 = -1¹/₄(x + 4)
y - 7 = -1¹/₄(x) - 1¹/₄(4)
y - 7 = -1¹/₄x - 5
+ 7 + 7
y = -1¹/₄x + 2
y - 7 = -1¹/₄(x - (-4))
y - 7 = -1¹/₄(x + 4)
y - 7 = -1¹/₄(x) - 1¹/₄(4)
y - 7 = -1¹/₄x - 5
+ 7 + 7
y = -1¹/₄x + 2
