Hello there!
A positive slope is represented in a linear equation by a positive coefficient behind the x term. A positive slope means that the graph is on an increasing interval as x approaches +∞. In a more simple way, a positive slope means that the graph is going up from left to right.
A negative slope is represented in a linear equation by a negative coefficient behind the x term. A negative slope means that the graph is on a decreasing interval as x approaches +∞. In a more simple way, a negative slope means that the graph is going down from left to right.
The x intercept(s) of a graph are where the graph touches the x-axis. These are also known as the zero(s) OR solution(s) of the function.
The y intercept(s) of a graph are where the graph touches the y-axis.
I hope this helps!
Best wishes:)
D is the rate of change, and A1 means the first term, ace of one is another way of saying it. You subtract 3 every time so the first three terms are 21, 18, and 15
2a^2b^5 is the answer ....
That is true
I graphed it on Desmos
Answer:
4. y+3=-1/3(x-9) 6a. 15x-y=0 6b. $150
Step-by-step explanation:
4.
Point slope form formula: y-y1=m(x-x1)
Includes origin and point (9,-3)
m= y2-y1/x2-x1
-3-0/9-0= -3/9=-1/3
slope= -1/3
Since we already have the point (9,-3),
enter the information above into the point slope form formula.
y-(-3)=-1/3(x-9)
<u>y+3=-1/3(x-9)</u>
6.
3h--> $75
1h--> $15
a)
Standard form: Ax + By = C
m(slope)=15
y=15x
y-15x=0
-15x+y=0
<u>15x-y=0</u>
b)
<u>10 hours of work---> $150</u>
