Answer:
a
Step-by-step explanation:
Recall that the "point-slope" form of a linear equation may be expressed as
y = mx + b,
where m is the gradient.
If m is negative, the gradient is negative.
If m is positive, the gradient is positive.
In our case, if we consider option A,
x + 3y = -2 (rearranging)
3y = -x -2
y = (-1/3) x - (2/3)
if we compare this to the general equation at the top, we can see that
gradient, = m = (-1/3) which is negative.
hence option a has a negative gradient.

Evaluate the expression 
where m=5 and n=4
We replace the value of m and n to evaluate
m=5 and n=4
50 + 4 = 54
The value of the given expression is 54 when m=5 and n= 4
Answer:
x = 2
Step-by-step explanation:
Answer:
30°,60°,90°
Step-by-step explanation:
<u>Let </u><u>:</u><u>-</u><u> </u>
<u>As </u><u>we</u><u> know</u><u> </u><u>:</u><u>-</u><u> </u>
<u>So </u><u>that</u><u> </u><u>,</u>
- x + 2x + 90 = 180
- 3x = 90
- x = 90/3
- x = 30
