2a. Determine the equation of the line connecting the points (0, -1) and (2, 3) *
Sauron [17]
First create the equation y=Mx+ B

B is the y intercept so when y = 0, B = -1.

Now we have y=Mx - 1

The slope is M. We can calculate this by using the formula M = (y2 -y1) / (x2 - x1)

Use the points (0, -1) and (2,3) for these values. So y2 = 3, y1 = -1, x2 = 2, x1 = 0

Plug them into the equation and solve

M = (3 + 1) / (2 - 0)
M = 4/2 = 2

Now we have the equation y = 2x - 1

Next to figure out if the points given are on the line you take the values and plug them into your equation like so: 4 = 2(-2) - 1

2(-2) - 1 does not equal 4 so this point does not fall on this line. Follow this same procedure for the next point given.

DENIUS [597]

Hi,

\frac{x^{a} }{x^{b} } =x^{a-b}

a)

\frac{x^{7} }{x^{3} }= x^{7-3} = x^{4}

b)

\frac{y^{5} }{y^{4} } = y^{5-4} = y^{1} = y
