the lines are perpendicular because they're crossing each other
X + 4y = 4
-x + 2y = 8
x + 4y - x + 2y = 4 + 8
6y = 12
y = 2
x + 4(2) = 4
x + 8 = 4
x = -4
(x,y)
(-4,2)
Answer:
2^-15 or 1/2^15
Step-by-step explanation:
3*-5 is -15 so that makes it 2^-15
Apply the exponent rule a^-b = 1/a^b
That changes it to 1/2^15

The equation of the line is y = -7/5x + 56/5
<h3>Equation of a line</h3>
The formula for expressing equation of a line is given as y = mx + b
where
m is the slope
b is the y-intercept
Given the coordinates A(8, 0) and (3, 7)
Determine the slope
Slope =7-0/3-8
Slope = -7/5
For the intercept
0 = -7/5(8) + b
b = 56/5
Hence the equation of the line is y = -7/5x + 56/5
