Answer:
see explanation
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 ) = (- 2, - 6) and (x₂, y₂ ) = (2, - 3) ← 2 points on the line
m = = , thus
y = x + c ← is the partial equation
To find c substitute either ot the 2 points into the partial equation
Using (2, - 3), then
- 3 = + c ⇒ c = - 3 - = -
y = x - ← equation of line
<em>B) -7x + 7y = -49</em>
This is a y=x plot/line shifted by 7 units.
This can also be verified plugging in the values of x=0,y=-7 and x=7,y=0. The only equation which satisfies these points in Equation B. These points have been chosen as they're the intercepts of this plot.
i think the answer is a
a yard = 3 feet
1 foot * 3 = yard
277 miles
224+17+36=277
(3, 1), (9, -1), (7, -4), and (1, -2)
(-1, 3), (5, 1), (3, –2), (–3, 0)
+4 +4 +4 +4
(3, 3), (9, 1), (7, -2), (1, 0)
-2 -2 -2 -2
(3, -1), (9, -1), (7, -4), (1, -2)
