2 answers:
Answer:
Step-by-step explanation:
The slope of a line can be found using the following formula:
Where (x₁,y₁) and (x₂,y₂) are the points on the line.
We are given the points (12,7) and (5,9). Therefore:
Substitute the values into the formula.
Solve the numerator.
- Subtract 7 from 9
- 9-7=2
Solve the denominator.
- Subtract 12 from 5
- 5-12= -7
This fraction cannot be reduced further, so it is the answer.
The slope of the line is -2/7

Answer:
<em>The graph of </em>y + 1 = −3/5 (x − 4)<em> would be a straight line. The graph figure is attached below.</em>
Step-by-step explanation:
As the linear equation y + 1 = −3/5 (x − 4) is given.
Since y-y₁ = m (x - x₁) is the Point-slope form is the general form y-y₁=m(x-x₁) for linear equations.
Hence, from the linear equation we can determine the slop which is m = -3/5
Also, when we put x = 0 in the linear equation, we determine the y-intercept as follows:
y + 1 = −3/5 (x − 4)
y + 1 = -3/5(-4) ∵x = 0
y = 12/5 - 1
y = 7/5
y-intercept: 7/5
Hence,
