The line whose slope is 4 and intersects the line 2x - 4y = 8 at x = 6 has the equation: a. y = 4x + 6 b. y = 4x + 1 c. y = 4x - 23

2x - 4y = 8   →   -4y = -2x + 8   →   y = - 2

We know the slope (m) = 4, need to find y-intercept (b)

y = 4x + b

- 2 = 4x + b

- 2 = 4(6) + b

3 - 2  = 24 + b

1 = 24 + b

-23 = b

Equation: y = 4x - 23

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
