Answer: [tex]\textsf{y = -1.75x - 11.75}[/tex]
-------------------------------------------------------------------------------------------------------------
Given: [tex]\textsf{Goes through (-5, -3) and parallel to 7x + 4y = 10}[/tex]
Find: [tex]\textsf{The equation in slope-intercept form}[/tex]
Solution: We need to first solve for y in the equation that was provided so we can determine the slope. Then we plug in the values into the point-slope form, distribute, simplify, and solve for y to get our final equation.
Subtract 7x from both sides
- [tex]\textsf{7x - 7x + 4y = 10 - 7x}[/tex]
- [tex]\textsf{4y = 10 - 7x}[/tex]
Divide both sides by 4
- [tex]\textsf{4y/4 = (10 - 7x)/4}[/tex]
- [tex]\textsf{y = (10 - 7x)/4}[/tex]
- [tex]\textsf{y = 10/4 - 7x/4}[/tex]
- [tex]\textsf{y = 2.5 - 1.75x}[/tex]
Plug in the values
- [tex]\textsf{y - y}_1\textsf{ = m(x - x}_1\textsf{)}[/tex]
- [tex]\textsf{y - (-3) = -1.75(x - (-5))}[/tex]
Simplify and distribute
- [tex]\textsf{y + 3 = -1.75(x + 5)}[/tex]
- [tex]\textsf{y + 3 = (-1.75 * x) + (-1.75 * 5)}[/tex]
- [tex]\textsf{y + 3 = -1.75x - 8.75}[/tex]
Subtract 3 from both sides
- [tex]\textsf{y + 3 - 3 = -1.75x - 8.75 - 3}[/tex]
- [tex]\textsf{y = -1.75x - 8.75 - 3}[/tex]
- [tex]\textsf{y = -1.75x - 11.75}[/tex]
Therefore, the final equation in slope-intercept form that follows the information that was provided is y = -1.75x - 11.75
