C. y =4 is the correct anwser
Here, take any points (0, -2) ((1, -6)
Now, slope (m) = -6 - (-2) / 1 - 0 = -6+2 / 1 = -4
Now, y - y1 = m(x - x1)
y - (-6) = -4(x - 1)
y + 6 = -4x + 4
y = -4x - 2
In short, Your Equation would be y = -4x - 2
Hope this helps!
-z = 80
You cannot submit an equation with a negative letter ( -z ) so we have to cancel the negative.
To cancel negatives in the equation, we multiply both sides by -1.
-z * -1 = 80 * -1
z = -80
Answer: z = -80
Answer:
x=4
y=3
Step-by-step explanation:
-0.8x+1.3y=0.7,3.2x−2.5y=5.3
-0.8x+1.3y=0.7
x=−1.25(−1.3y+0.7)
x=1.625y−0.875
3.2(1.625y−0.875)−2.5y=5.3
5.2y−2.8−2.5y=5.3
2.7y−2.8=5.3
2.7y=8.1
y=3
x=1.625×3−0.875
x=<u> </u><u>39-7</u><u> </u>

x=4
