First we need to find the slope
y2-y1/x2-x1
-6-4/-3-2
-10/-5 <---this can be simplified
Slope=2
Point slope:
y-y1=m(x-x1)
Now take the first pair of coordinates and plug them in their proper spots it helps to label them then plug in
y1=4
x1=2
m=slope=2
Now plug them in our final answer would be :
y-4=2(x-2)
Slope intercept:
<span>y = mx + b
</span><span>where:
m is the slope of the line
b is the y-intercept of the line
Slope is known
y=2x+b
To find the b you pick one of the given coordinates let's do (2,4)
Plug them into what we have
y=2x+b
4=2(2)+b
solve for b
4=4+b
subtract 4 from both sides
b=0 therefore the equation would simply be
y=2x</span>
Answer:
109°
Step-by-step explanation:
x+48+23=180
x=180-71
<h3>x=109°</h3>
Answer:
Step-by-step explanation:

d) Let the cost of one group lesson be x and one private lesson be y

If it's absolute value, then it is 1.1
Just the positive number.
Because no matter what the product will always be a 2 digit number.
hope this helped :)
