Answer:
a) (-2,2), (-1,-1), (1,-1), (3,7)
b) x=1.4
Answer:
The answers are that the x-coordinate is 3, the y-coordinate is 4 and it is in quadrant I
Step-by-step explanation:
To find these answers, start by solving the system. We can do this by multiplying the second equation by 2 and adding them together.
8x + 6y = 48
4x - 6y = -12
-------------------
12x = 36
x = 3
Next, find the y value by plugging in the x value to either equation and solving.
2x - 3y = -6
2(3) - 3y = -6
6 - 3y = -6
-3y = -12
y = 4
<span>Complete the slope-intercept form equation of the line with slope − 8 that passes through the point (0,−2) (don't mention (0,-2) more than once)
y = mx + b, with m= -8, comes out to y = -8x + b.
Subst. 0 for x and -2 for y and then calculate b: -2 = 0 + b => b = -2
Then the equation is y = -8x - 2.</span>
