Answer:
y = 2x - 5
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 )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 2, - 9) and (x₂, y₂ ) = (6, 7)
m = (7 + 9) / (6 + 2) = 16/8 = 2
y = 2x + c ← is the partial equation
to find c use either of the 2 points
using (6, 7), then
7 = 12 + c ⇒ c = 7 - 12 = - 5
y = 2x - 5 ← equation in slope-intercept form
Answer:
15
Step-by-step explanation:
To get the next number you have to subtract by 9, 51-9=42, 42-9=33, 33-9=24, and so 24-9=15. The pattern is n-9 (n=previous number) and the answer is 15
Answer:
y = -x + 9
Step-by-step explanation:
The correct answer is c=5. hope this helps.
Answer:
= x^7
Step-by-step explanation:
When the bases are the same, and we are multiplying, we can add the exponents
x^a* x^b = x^(a+b)
x^3•x^4= x^(3+4)
= x^7
