Answer:
y= -3x-12
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is its gradient and c is its y-intercept.
Given that the slope is -3, m= -3.
Substitute the value of m into the equation.
y= -3x +c
Now, substitute the given coordinates into the equation.
When x= -5, y= 3,
3= -3(-5) +c
3= 15 +c
c= 3 -15
c= -12
Hence, the equation of the line is y= -3x-12
Answer:
A
Step-by-step explanation:
Substitute n = 9 into the nth term rule
A(9) = - 15 + 2(9 - 1) = - 15 + 2(8) = - 15 + 16 = 1 → A
Answer:
11
Step-by-step explanation:11-4=7+4 + 11
False...it does not include 3....it includes only numbers less then 3.
For it to include 3, u would need an equal sign in there..
Y < = 3...(thats less then or equal)...this would include 3
