Answer :
Answer:
y = [tex]\frac{7}{9}[/tex] x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (9, - 1) and (x₂, y₂ ) = (0, - 8)
m = [tex]\frac{-8+1}{0-9}[/tex] = [tex]\frac{-7}{-9}[/tex] = [tex]\frac{7}{9}[/tex]
Note the line crosses the y- axis at (0, - 8) ⇒ c = - 8
y = [tex]\frac{7}{9}[/tex] x - 8 ← equation of line
Answer: y=(7/9)x-8
Step-by-step explanation:
y=mx+b line equation
m= y¹-y²/x¹-x²
m= (-1)-(-8)/9-0
m= -1+8/9
m=7/9
y=(7/9)x+b
To find b put the value of point (9-1) in the equation
-1= (7/9)(9)+b
-1= 7+b
-1-7=b
-8=b
