1. x = 3

2. y = (-2/3)x + 2

3. y = -2

4. y = 3x + 5

5. y = -2x + 5 (im assuming the minus is an equal sign?)

6. y = 3

Step-by-step explanation:

1. for this question, look at the graph, and find the slope. there is no slope, right? because its just a straight vertical line. this is called an undefined slope. you only know the x value, which is 3, and the y values are infinite. since you cant really make an equation, it would just be x = 3, because that's all you know from the graph.

2. For this graph, you have to count boxes. Slope is "rise over run", which means the number of boxes you go up, is the numerator for the slope, and the number of boxes you go to the left or right is the denominator. So in this graph, put your finger on any point on the line you know, like (3,0). Then, count how many boxes you have to go up and to the left to get to another point, like (0,2). You went up 2 boxes, and went to the left 3 times right? So the slope would be 2/3, but since you went to the LEFT, its negative. So that's the slope. The y intercept, is just visible on the graph. You can see the line intersects the y line at (0,2), so the y intercept is 2.

3. This is the same as number one, but you only know the one y value, which is -2. This graph is called a zero slope, because it doesn't go up or down. So since all you know is y = -3, that's your forumla.

4. Follow the same steps as number 2! you'll get the hang of it :) (start from a point that's really clear, like (-1,2), which is right on the line, and then count to antoher point, like (0,5), which is also the y intercept.

5 & 6. These questions just give you the slope, and the y intercept, so its easy! the formula is y = mx + b. m is the slope, and b is the intercept! just plug in and you get the answer :)

it would to have a graph or something ! but i had this question so its false

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
