Answer:
y=-x+9
Step-by-step explanation:
The answer above is written in slope-intercept form because it is the easiest form to graph (in my opinion); slope-intercept form is y=mx+b, where m is slope and b is the y-intercept. However, to get the answer, you must first use slope-point. Slope-point is . So, plug in the point and slope into the formula. This gives the equation, y-6=-1(x-3). Then, solve the equation for the answer of y=-x+9.
On a graph, the y-intercept will be 9. So, the line will cross the y-axis at a value of 9. Additionally, the slope is -1. So, y will increase by one and x will decrease by one. This means that the line will look like it decrease left to right.
Inverse variation: y=k/x
1. plug in the values: (15,1)
1=k/15
2. solve for k
3. Now, plug in what you can for the second point: (n,5)
5=k/n (if you do the step above, you will know “k”.
4. Solve for “n”
Answer:
2(x+3) (x^2 + 5)
Step-by-step explanation:
Supplementary angles are angles that together, for an angle of 180°. Straight lines are also 180°, so what you need to look for in this exercise are angles, next to eachother, on the same straight line.
those are:
1,2
1,4
2,3
5,6
5,8
6,7
7,8
3,4
so the right answers are option 1 and 2
