Answer:
I'm going to do 1 as an example and using what I've taught you, you have to do the rest. Hope my explanation helps.
Step-by-step explanation:
We are given the points (-2, -4) and (-1, -1)
We need to find the slope.
The equation to do so is y2 - y1 / x2 - x1
lest say:
-2 is x1
-4 is y1
-1 is x2
-1 is y2
-1 - (-4) / -1 - (-2)
3/1 = 3
slope (m) = 3
We already know the y-intercept is 2
The equation of a line is y = mx + b
For this problem we just have to substitute what we already know.
y = (slope)x + y-intercept
y = 3x + 2
*TIP*
If the y-intercept is negative, let's say: b = -5 (using slope 8)
the equation will be y = 8x - 5
Hope this helps. I wish you all the best. :)
Answer: x= 3,2
Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
The midpoint between these two would be -7, as you would add these two numbers, and then divide by two.
Answer:
Step-by-step explanation:
For the orange table:
<em> </em>Substitute the corresponding values of <em>x</em> into the function 
, then:
For a:
x=0
For b:
x=2
For c:
x=4
For the blue table:
<em> </em>Substitute the corresponding values of <em>x</em> into the function 
, then:
For d:
x=0
For e:
x=2
For f:
x=4
Answer:
Step-by-step explanation:
Find, find the total increase in salary for 7 years;
If 1 year = $4,000
7 years = ?
=7*4000
=28,000 in total
Original salary = $169,300
Add the total increase in salary to the original salary;
169,300 + 28,000 = 197,300
Therefore, in 7 years, the salary would be $197,300
