Answer:
y = 2/3 x - 2.
Step-by-step explanation:
The slope of the line = rise/run = 2/3 and the y-intercept is at y = -2.
The equation is y = mx + c where the slope m = 2/3 and c = -2.
Answer:
4
Step-by-step explanation:
(5x + 4y = 8) 2 = 10x+8y=16
(2x - 3y = 17)5 = 10x-15y=85
we can pick one of the equation and multiply it by a -1 which equals:
10x+8y=16
-10x+15y=-85
and -10 and 10 cancels out.
add 8 and 15 = 23y
add -85 and 16 = -69
divide -69 by 23 whcih equals -3
plug in the y value in any of the equation, i chose 2x - 3y = 17
you get 2x+9=17
2x=8
x=4
-225/-15 will give us a positive answer since we are dividing by two negative values, so we can rule out answers 1 and 2 first off.
then we solve to find the answer -225/1*-1/15 = 15
hope this helps! thanks!
