Please please help me out

Answer 1

Answer:

y + 9 = - 10(x - 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (1, - 9) and (x₂, y₂ ) = (- 10, 101)

m = $\frac{101+9}{-10-1}$ = $\frac{110}{-11}$ = - 10

Using (a, b) = (1, - 9), then

y - (- 9) = - 10(x - 1), that is

y + 9 = - 10(x - 1)
