1, 3, 4 i hope this helps ;)
Step-by-step explanation:
Answer:
The equation of line is: 
Step-by-step explanation:
We need to find an equation of the line that passes through the points (-6, -2) and (-3, 2)?
The equation of line in slope-intercept form is: 
where m is slope and b is y-intercept.
We need to find slope and y-intercept.
Finding Slope
Slope can be found using formula: 
We have 
Putting values and finding slope

So, we get slope: 
Finding y-intercept
Using point (-6,-2) and slope
we can find y-intercept

So, we get y-intercept b= 6
Equation of required line
The equation of required line having slope
and y-intercept b = 6 is

Now transforming in fully reduced form:

So, the equation of line is: 
Answer:
The answer is 148.6666667
Step-by-step explanation:
1) Set a linear quation

2) Cross multiply

3) Multiple the right side

4) Divide both side by 15

5) Solve the linear equation

Answer:
Sum of 3 angles in a triangle=180
x+55+72= 180
x+ 127=180
x= 180-127
x= 53
Step-by-step explanation:
-7(-3r+2)=3r-6
Distribute the - 7
21r-14=3r-6
Add 14
21r=3r+8
Subtract 3r
18r=8
Divide 18r by 8
2.25 should be the answer to r.
