I need help on this saturday guys

The point-slope form:

y-y_1=m(x-x_1)

m - slope

(x₁, y₁) - the point

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (5, 4) and (2, -2). Substitute:

m=\dfrac{-2-4}{2-5}=\dfrac{-6}{-3}=2

y-4=2(x-5) - <em>point-slope form</em>

y-4=2x-10        <em>add 4 to both sides</em>

y=2x-6  - <em>slope-intercept form</em>

y=2x-6      <em>subtract 2x from both sides</em>

-2x+y=-6      <em>change the signs</em>

2x-y=6   - <em>standard form</em>

-------------------------------------------------------------------

From the table we have two points (1, 3) and (2, 7). SubstituteL

m=\dfrac{7-3}{2-1}=\dfrac{4}{1}=4

y-3=4(x-1)   - <em>point-slope form</em>

y-3=4x-4     <em>add 3 to both sides</em>

y=4x-1    - <em>slope-intercept form</em>

y=4x-1      <em>subtract 4x from both sides</em>

-4x+y=-1     <em>change the signs</em>

4x-y=1    - <em>standard form</em>

3 our of 5 in two equivalent forms
sammy [17]
Hello!

3 out of 5 looks like this as a fraction:

3/5

We cannot divide this further as both the numerator and the denominator are odd numbers, so we must multiply to get an equivalent fraction:

3/5 = 6/10 = 60/100

3/5 is also equivalent to 0.2 as a decimal or 20% as a percentage.
