Answer:
x= ± sqrt [ y/a]
Step-by-step explanation:
y = ax^2
y/a = x^2
x^2 = y/a
x= ± sqrt [ y/a]
The y intercept is (0,0) and the slope is 4
Answer:
Step-by-step explanation:
There is no solution, because the lines do not intersect.
The standard form:

The slope-intercept form:

m - slope

b - y-intercept (0, b).
We have the point (0, 43) → b= 43.
Next point (2, 55). Substitute to the slope formula:

Therefore we have:
<em>subtract 6x from both sides</em>
