Answer:
NO
Step-by-step explanation:
Direct variation describes a simple relationship between two variables . We say y varies directly with x (or as x , in some textbooks) if: y=kx. for some constant k . This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.
also if it would be the same it would be (0,0) then (2,4) and finally (3,6) now that it would be a constant one.

Step-by-step explanation:
<u>Line A</u>
gradient = 4
x-intercept = -1
y-intercept = 4
<u>Line B</u>
gradient = -3
x-intercept = -1
y-intercept = -3
<u>y + 8x = - 72</u>
x-intercept = -9
y-intercept = -72

Answer:
x = 11.61 to the nearest hundredth.
Step-by-step explanation:
√(2x - 2) = x - 7
Square both sides:
2x - 2 = (x - 7)^2
2x - 2 = x^2 - 14x + 49
x^2 - 16x + 51 = 0
using the quadratic formula we get x = 4.39 , 11.61.
With radical equations we can get extraneous roots so we check these values:
X = 4.39 :
√(2(4.39) - 2) = 2.61
4.39 - 7 = -2.61 so 4.39 is NOT a root.
x = 11.61
√(2(11.61) - 2) = 4.61
11.61 - 7 = 4.61 so this is a root.
If your looking for the y-intercept it is 4
