write an equation of the line that satisfies the given conditions. give the equation (a) in slope intercept form and (b) in standard form. m=-7/12 ,(-6,12)

Respuesta :

Given the slope of the line:

[tex]m=-\frac{7}{12}[/tex]

And this point on the line:

[tex](-6,12)[/tex]

(a) By definition, the Slope-Intercept Form of the equation of a line is:

[tex]y=mx+b[/tex]

Where "m" is the slope and "b" is the y-intercept.

In this case, you can substitute the slope and the coordinates of the known point into that equation, and then solve for "b", in order to find the y-intercept:

[tex]12=(-\frac{7}{12})(-6)+b[/tex][tex]12=\frac{42}{12}+b[/tex][tex]\begin{gathered} 12=\frac{42}{12}+b \\ \\ 12=\frac{7}{2}+b \end{gathered}[/tex][tex]\begin{gathered} 12-\frac{7}{2}=b \\ \\ b=\frac{17}{2} \end{gathered}[/tex]

Therefore, the equation of this line in Slope-Intercept Form is:

[tex]y=-\frac{7}{12}x+\frac{17}{2}[/tex]

(b) The Standard Form of the equation of a line is:

[tex]Ax+By=C[/tex]

Where A, B, and C are integers, and A is positive.

In this case, you need to add this term to both sides of the equation found in Part (a), in order to rewrite it in Standard Form:

[tex]\frac{7}{12}x[/tex]

Then, you get:

[tex]\frac{7}{12}x+y=\frac{17}{2}[/tex]

Hence, the answers are:

(a) Slope-Intercept Form:

[tex]y=-\frac{7}{12}x+\frac{17}{2}[/tex]

(b) Standard Form:

[tex]\frac{7}{12}x+y=\frac{17}{2}[/tex]
