Given:
A straight-line graph has gradient 4 and crosses the y axis at (0, −3).
To find:
The equation of the given graph.
Solution:
The slope intercept form of a line is:
...(i)
Where, m is the slope of the line and b is the y-intercept.
A straight-line graph has gradient 4. It means the slope of the line is 4.

Line crosses the y axis at (0, −3). So, y-intercept is -3.

Putting m=4 and b=-3 in (i), we get


Therefore, the equation of the given line graph is
.
The equation was just flipped around, it will equal the same no matter what.
I hope this helps!! :)
Step-by-step explanation:
For the square roots, write the radicand as a multiple of a perfect square. For example:
√27 = √(9 × 3) = 3√3
√72 = √(36 × 2) = 6√2
√¾ = √(¼ × 3) = ½√3
For the cube roots, write the radicand as a multiple of a perfect cube. For example:
∛16 = ∛(8 × 2) = 2∛2
∛(27/8) = 3/2
Answer:5/2
