The equation has a y intercept and a steadily decreasing value
So that makes it linear (not all linear equations have a y intercept but they do all have a steady increase or decrease)
The y intercept is -6 so we know the equation will have a y intercept of -6
Looking at at graph, we also see for everytime x increases one, that y decreases -3
So that gives the equation a rate of -3x
So the equation is y=-3x-6
So your answer is C
Answer:
Step-by-step explanation:
perp. 1/3
y - 0 = 1/3(x - 9)
y = 1/3x - 3
Answer:
y = 6x - 4
Step-by-step explanation:
(2, 8) & (1, 2)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(2 - 8) / (1 - 2)
Simplify the parentheses.
= (-6) / (-1)
Simplify the fraction.
-6/-1
= 6
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 6x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (1, 2). Plug in the x and y values into the x and y of the standard equation.
2 = 6(1) + b
To find b, multiply the slope and the input of x(1)
2 = 6 + b
Now, subtract 6 from both sides to isolate b.
-4 = b
Plug this into your standard equation.
y = 6x - 4
This is your equation.
Check this by plugging in the other point you have not checked yet (2, 8).
y = 6x - 4
8 = 6(2) - 4
8 = 12 - 4
8 = 8
Your equation is correct.
