Answer:

Step-by-step explanation:
We are given;
- A point where the line is passing through as (3, -4)
- The slope of the line -1/2
We are required to determine the equation of the line;
- Note that, one way we can get the equation of a straight line is when we are given a point where the line is passing through and its slope.
- Thus, in this case, we can determine the equation;
Taking another point (x, y)
Then; (x, y) , ( 3, -4) and slope -1/2 can give us the equation;
That is;

Cross multiplication;


Combining the like terms;

Thus, the equation of the line is; 

thats the slope, you can also get a decimal out of it
Answer: -4

Answer:
4x - 5y + 30 = 0
Step-by-step explanation:
When a slope of a line and a point passing through it is given then we use slope - one point form to determine the equation of the line.
It is given by:

where
is the slope of the line and
is the point passing through it.
Here
and
.
Substituting in the equation we get



Answer:
b = 50%
Step-by-step explanation:
P(Heart or Club)
= P(Heart) + P(Club)
= 13/52 + 13/52
= .25 + .25
= .5 --> 50%
