Write the equation of a line that is parallel to 3x+2y=10 and passes through the point (4,-5). Answer in slope-intercept form.

I need a bit of help with this! ty c:

Respuesta :

The equation of line is:

[tex]y = \frac{-3}{2}x+1[/tex]

Further explanation:

The standard form of equation in point-slope form is:

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

Given equation is:

3x+2y=10

We have to convert it into point slope form, for which we have to isolate y on one side of equation

[tex]3x+2y = 10\\2y = -3x +10\\y = \frac{-3}{2}x + \frac{10}{2}\\y = \frac{-3}{2}x + 5[/tex]

Comparing with standard form:

m = -3/2

As the new line is parallel to given line, their slopes will be equal

So,

[tex]y = \frac{-3}{2}x+b[/tex]

To find the value of b, putting the given point (4,-5) in equation

[tex]-5 = \frac{-3}{2}(4)+b\\-5 = -6+b\\b = -5+6 \\b = 1\\So\ the\ equation\ is:\\y = \frac{-3}{2}x+1[/tex]
