y = mx + b
m = slope
b = y-intercept
Since it is parallel to the equation y = 3x it means that the equation that goes through point (-1, 0) has the same slope (3x)
To find the b plug the x and y of point (-1, 0) into the equation: y = 3x + b then solve for b
0 = 3(-1) + b
0 = -3 + b
0 + 3 = (-3 + 3) + b
3 = b
so...
y = 3x + b
Hope this helped and made sense!

Answer:
y = 3x - 3
Step-by-step explanation:
Since our line is parallel to y = 3x, our slope should be 3. We also have the points (-1, 0).
From here, we can use the point-slope form (how convenient):
y - y₁ = m(x - x₁), where (x₁, y₁) is the given coordinate on the line, and m is the slope of the line
Plug in: y - 0 = 3(x - 1)
We could leave it here, but we should convert this line into the more commonly-seen slope-intercept form.
Distribute: y - 0 = 3x - 3
Identity: y = 3x - 3
