Answer:

  y = 4/3(x +3)

Step-by-step explanation:

This sort of question is easily answered by making use of the point-slope form of the equation of a line:

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

You are given (h, k) = (-3, 0) and m = 4/3. Putting those into the above form gives ...

  y -0 = 4/3(x -(-3))

  y = 4/3(x +3) . . . . . . point-slope form equation

__

<em>Additional comment</em>

You can use the distributive property to eliminate the parentheses. That puts the equation into slope-intercept form.

  y = 4/3x +(4/3)(3)

  y = 4/3x +4 . . . . . . slope-intercept equation

__

You may find it useful to remember some different forms of the equation for a line:

  y = mx +b . . . . . line with slope m and y-intercept b

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

  ax +by = c . . . . standard form equation of a line, where a > 0, and a, b, c are mutually prime integers

Which expression is equal to 4/8
givi [52]
<h2>Fractions</h2>

Which expression is equal to \large\tt \frac{4}{8}?

Option 1

  • \large \tt 4  \times \frac{1}{2}  =  \frac{4}{1}  \times  \frac{1}{2}  =   \red{\frac{4}{2}}

Option 1 is not equal to \large\tt \frac{4}{8}

Option 2

  • \large \tt 3 \times  \frac{1}{5}  =  \frac{3}{1}  \times  \frac{1}{5}  =   \red{\frac{3}{5}}

Option 2 is not equal to \large\tt \frac{4}{8}

Option 3

  • \large \tt 3  \times \frac{1}{8}  =  \frac{3}{1} \times  \frac{1}{8}   =   \red{\frac{3}{8}}

Option 3 is not equal to \large\tt \frac{4}{8}

\huge{\overline{\qquad\qquad\qquad\qquad \: \: \: }}

Option 4

  • \large \tt 4  \times \frac{1}{8}  =   \frac{4}{1}  \times  \frac{1}{8}  =   \green{\frac{4}{8}}

Therefore, option 4 is equal to \large\tt \frac{4}{8}

Solnce55 [7]
If so, start by factoring the numerator. Then cancel any common term in the numerator and denominator. If you end up with no denominator, then use the original denominator. Set it equal to zero and solve for x. That value of x will be the restriction.
