Choose the system of equations that matches the following graph:

Picture of coordinate plane with line y equals 1 over 4 x plus 1 and line y equals negative 3 over 4 x plus 9. They intersect at 8, 3.

x − 4y = −4
3x + 4y = 36

x + 4y = −4
3x − 4y = 36

x + 4y = −4
3x + 4y = 36

x − 4y = −4
3x − 4y = 36

step-by-step explanation:

where is the questions

b

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 ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

step-by-step explanation:

its 512 because parenthesis and to the 2nd power is 512 so it will be 512

a ≈ 172.05
