Answer:
y = - 8x - 4
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 )
Here m = - 8, then
y = - 8x + c ← is the partial equation
To find c substitute (- 1, 4 ) into the partial equation
4 = 8 + c ⇒ c = 4 - 8 = - 4
y = - 8x - 4 ← equation of line
Answer:
y = -2x+13
Step-by-step explanation:
2X + Y = 13
The slope intercept form is y = mx+b where m is the slope and b is the y intercept
Subtract 2x from each side
2x-2x+y = -2x+13
y = -2x+13
The diagonal of a square forms two 45-45-90 triangles.
The ratios of the lengths of the sides of a 45-45-90 triangle are

The hypotenuse is

times the length of the legs.
Each leg is the length of the hypotenuse divided by

.
