Answer: Income is the money coming in; expenses are the money going out
Answer: 6.3
Step-by-step explanation:
1.8 + 45 tenths equal 6.3
Equation in point slope form is written as:
y = mx + c, where m is the slope of the line and c is the y-intercept
To determine the equation when slope is given and (x,y) coordinates are given, use the below formula:
(y - y₁) = m × (x - x₁) .................. (i)
We have been given that m = 3, x₁ = 2 and y₁ = 1)
Substituting the values of m, x₁ and y₁ in (i)
(y - 1) = 3 × (x-2)
⇒ y - 1 = 3x - 6
⇒ y = 3x - 5
So the required equation is y = 3x -5, here 3 is the slope and -5 is the y-intercept
Step-by-step explanation:
a general line equation is
y = ax + b
"a" being the slope is the line, "b" being the y-intercept (the y value when x = 0).
we see from the 2 marked points (by we could choose any points on the line) that
y changes by 2 units, when x changes by 3 units.
so the slope is 2/3.
we use one point (1, 2) to solve for b
2 = 2/3 × 1 + b = 2/3 + b
6/3 = 2/3 + b
4/3 = b
and the full equation is
y = 2/3 x + 4/3
