Answer:
Step-by-step explanation:
Given that when you add two numbers together the result is 3.
The greater of the number is given as a.
Let "x" represent that lesser number.
Thus:
To make x the subject of the formula. Subtract a from both x.
Therefore, the expression that represents the lesser number, x, is:
<u>Answer: </u>
The equation in slope intercept form for (5,9) and (6,8) is y = 3x-10
<u>Solution: </u>
Given that (5,9) and (6,8)
Here,
We know the slope of an equation is given by y = mx+c
To find the value of m, we use the below given formula
Substituting the values we get,
m = 3
Putting the value of m in the slope intercept form we get,
y = 3x+c
To find the value of c, we substitute the value of x and y from any two given point. Let’s take x = 5 and y = 5
5 = 3(5) + c
5 = 15 +c
5-15 = c
c = -10
Therefore the slope intercept equation becomes y = 3x -10
