Help with number 7. we just started this unit so i'm clueless.. please help!

crimeas [40]

You first need to isolate the y
4x+9y=-108
9y=-4x-108 (subtract 4x from both sides)
y=-4/9x-12 (divide both sides by 9)
Then, by using the y=mx+b form, we can tell that the y-intercept is -12 so A

Hope this helps

What is the point-slope form of the line with slope 2/5 that passes through the point (-4, -7) ?

likoan [24]

Answer:

• General equation of a line:

${ \tt{y = mx + b}} \\$

m is the slope, m = 2/5
b is y-intercept

${ \tt{ - 7 = ( \frac{2}{5} \times - 4) + b }} \\ \\ { \tt{ - 7 = - \frac{8}{5} + b}} \\ \\ { \tt{b = - \frac{27}{5} }}$

• Therefore, equation of line is:

${ \tt{y = \frac{2}{5}x - \frac{27}{5} }} \\$
