In this equation, you have to treat the number in the bracket first on the basis of BODMAS
15 - [-3]- 4
Note that when two minuses come together the product is a plus sign.
15 +3 - 4
You have to add before you subract
18 - 4 =14
Therefore, 15- [-3] - 4 = 14.

Write the equation of the line parallel to<br> y=-2/3x+4 and through the point (–3, 15)
MrRa [10]
Parallel = same slope
y = -2/3x + b
Plug in point
15 = -2/3(-3) + b
15 = 2 + b, b = 13
Solution: y = -2/3x + 13

Find the equation of the line that goes through the point (0, 4) and is parallel to the line y=3x
den301095 [7]

\huge\boxed{\sf{Hi\;there!}}

Parallel lines have the same slope.

The given line has a slope of 3, therefore, the line parallel to the given line has a slope of 3.

Now, we have the slope of the line and a point that it passes through.

So, we can use the Point-Slope formula:

\bigstar \sf{y-y1=m(x-x1

\bigstar \sf{y-4=3(x-0)

\bigstar \sf {y-4=3x

\bigstar \sf {y=3x+4

\huge\boxed{\boxed{Answer:\;y=3x+4}}}

\huge\bold{Hope\;it\;helps\;you.\;Good\;luck\;and\;have\;a\;nice\:day.}
