Answer:
x = 3 and y = -18
Step-by-step explanation:
y = -6x
y = -8x + 6
Both equations are equal to y. So,
y = -6x = -8x + 6
Solve for x first.
-6x = -8x + 6
Add 8x to both sides.
2x = 6
x = 3
Substitute x = 3 into y = -6x
y = -6 * 3
y = -18
Now, double check to see if this is correct.
y = -8x + 6
-18 = -8 * 3 + 6
-18 = -24 + 6
-18 = -18
x = 3 and y = -18 are correct.
I hope this helps! Feel free to ask any questions!

Answer:
The equation of the line would be y = -3/2x + 7/2
Step-by-step explanation:
In order to find this, we must first use the slope formula with the two point to find the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (5 - -1)/(-1 - 3)
m = 6/-4
m = -3/2
Now that we have the slope, we can use that and either point in point-slope form. Then we solve for y.
y - y1 = m(x - x1)
y + 1 = -3/2(x - 3)
y + 1 = -3/2x + 9/2
y = -3/2x + 7/2
