can you help me with math?

Definition of slope:

m = (y1 - y0) / (x1 - x0)

Standard form of line:

y = mx + b , where m is the slope and b is y-intercept

1. (2, 0) and (3, -3) = (x1, y1) and (x2, y2)

m = (0 + 3) / (2 - 3) = -3

2. The slope for x = 5 is undefined. It doesn't exist because x = 5 is a vertical line, and vertical lines don't have a slope.

3. Plug that right into your standard line equation! m = 2, and b = 3 so

y = 2x + 3

4. This time we need to solve for the y-intercept. Plug in your points and solve:

y = mx + b

0 = 7(-2) + b

b = 14

So

y = 7x + 14

1. m = (y2 - y1)/(x2 - x1) where 'm' is the slope.

(-3 - 0)/(3 - 2) = m = -3

2. When x = 5, you'll have a vertical line running up and down the y-axis at point 5 on the x-axis. The rule is: The slope of a vertical line is undefined and the slope of a horizontal line is zero.

3. Use the equation y = mx + b, where 'm' is the slope and 'b' is the y-intercept. You say the slope is 2 and the y-intercept is 3, so plug them in. Answer: y = 2x + 3.

4. Similar to number 3, except this time you have the x-intercept in the point (-2, 0). You also have the slope. Take these two figures and plug them into the equation "y = mx + b". You'll have

0 = 7(-2) + b. Solve this to find 'b':

0 = -14 + b

14 = b

Then take the 'b' that you now have, and the 'm' that you already had, and you'll be able to plug them into the y = mx + b equation to get:

y = 7x + 14
