Answer:

(5,-3)

Step-by-step explanation:

y+3 = 3x-15

y= -2x + 7

plulg y in

-2x+7+3 = 3x-15

combine like terms

-2x+10 = 3x-15

add 2x to both sides and add 15 to both

5x=25

x=5

y=-2(5) + 7

y= -10 + 7

y= -3

In the standard (x,y) coordinate plane, what is the slope of the line 4x+7y=9?

o-na [289]

Answer: -4/7

Step-by-step explanation:

To find the slope, let's change the equation to slope-intercept form.

$4x+7y=9$ [subtract both sides by 4x]

$7y=-4x+9$ [divide both sides by 7]

$y=-\frac{4}{7}x+\frac{9}{7}$

Now, we know the slope is -4/7.
