The answer is "The correct step are 1, 2 and 4 ".
Step-by-step explanation:
In the question some data is missing so, its correct question can be defined as follows:
In the given equation:
Lorena's steps should be evaluated
In Stage 1: It is right because it allocates – 3 to parentheses appropriately, , that's why she has 5k-6k+2-9=0
In Stage 2: It is right because in this term 5k and 2k are merged, that's why she got -k-7=0
In Stage 3: It is not right because the propagation property of fair treatment was not used.
In Stage 4: It is right because it multiplies the variable on one of the two sides by -1. So, k=-7 to get.
Answer:
y= 3x -4
Step-by-step explanation:
The equation of a line can be written in the form of y=mx +c, where m is the slope and c is the y-intercept. This is also known as the slope-intercept form.
Since the given equation is in the slope-intercept form, we can identify its slope from the coefficient of x.
Slope= -⅓
The product of the slopes of perpendicular lines is -1.
Slope of perpendicular line
= 3
Thus, the equation of the perpendicular line is given by:
y= 3x +c
Substitute a pair of coordinates that the line passes through to find the value of c.
When x= 3, y= 5,
5= 3(3) +c
5= 9 +c
<em>Minus 9 on both sides:</em>
c= 5 -9
c= -4
Hence, the equation of the perpendicular line is y= 3x -4.
