A line that passes through the points [tex]\((-4,10)\)[/tex] and [tex]\((-1,5)\)[/tex] can be represented by the equation [tex]\(y=-\frac{5}{3}(x-2)\)[/tex]. Which equations also represent this line? Select three options.

A. [tex]\(y=-\frac{5}{3} x-2\)[/tex]

B. [tex]\(y=-\frac{5}{3} x+\frac{10}{3}\)[/tex]

C. [tex]\(3 y=-5 x+10\)[/tex]

D. [tex]\(3 x+15 y=30\)[/tex]

E. [tex]\(5 x+3 y=10\)[/tex]



Answer :

To determine which equations also represent the given line [tex]\( y = -\frac{5}{3}(x-2) \)[/tex], let's analyze and compare each option.

Step-by-Step Solution:

1. Given Line Equation:
[tex]\[ y = -\frac{5}{3}(x - 2) \][/tex]
Let's expand this equation to see its standard form:
[tex]\[ y = -\frac{5}{3} x + \frac{10}{3} \][/tex]

2. Option 1: [tex]\( y = -\frac{5}{3}x - 2 \)[/tex]
Compare this with the given line's standard form [tex]\( y = -\frac{5}{3} x + \frac{10}{3} \)[/tex]:
[tex]\[ y \quad = \quad -\frac{5}{3}x \quad - 2 \][/tex]
This equation does not match [tex]\( y = -\frac{5}{3}x + \frac{10}{3} \)[/tex].

3. Option 2: [tex]\( y = -\frac{5}{3}x + \frac{10}{3} \)[/tex]
Compare this with the given line's standard form:
[tex]\[ y \quad = \quad -\frac{5}{3}x \quad + \frac{10}{3} \][/tex]
This equation matches [tex]\( y = -\frac{5}{3}x + \frac{10}{3} \)[/tex].

4. Option 3: [tex]\( 3y = -5x + 10 \)[/tex]
Rearrange to standard form [tex]\( y = mx + b \)[/tex]:
[tex]\[ 3y = -5x + 10 \][/tex]
Divide both sides by 3:
[tex]\[ y = -\frac{5}{3}x + \frac{10}{3} \][/tex]
This equation matches [tex]\( y = -\frac{5}{3}x + \frac{10}{3} \)[/tex].

5. Option 4: [tex]\( 3x + 15y = 30 \)[/tex]
Rearrange to standard form [tex]\( y = mx + b \)[/tex]:
[tex]\[ 15y = -3x + 30 \][/tex]
Divide both sides by 15:
[tex]\[ y = -\frac{1}{5}x + 2 \][/tex]
This equation does not match [tex]\( y = -\frac{5}{3}x + \frac{10}{3} \)[/tex].

6. Option 5: [tex]\( 5x + 3y = 10 \)[/tex]
Rearrange to standard form [tex]\( y = mx + b \)[/tex]:
[tex]\[ 3y = -5x + 10 \][/tex]
Divide both sides by 3:
[tex]\[ y = -\frac{5}{3}x + \frac{10}{3} \][/tex]
This equation matches [tex]\( y = -\frac{5}{3}x + \frac{10}{3} \)[/tex].

Hence, the equations that also represent the given line [tex]\( y = -\frac{5}{3} (x - 2) \)[/tex] are:
[tex]\[ \boxed{2, 3, 5} \][/tex]
