The equation of the line is y = 0.8x - 1.4 if the slope of the line is 0.8 and line passes through coordinates (-2,-3)
<h3>What is a straight line?</h3>
A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
The slope m = 0.8
The line passing through coordinates (-2,-3)
y = mx + c
y = 0.8x + c
Plug the point in the equation.
-3 = 0.8(-2) + c
c = -1.4
y = 0.8x - 1.4
Thus, the equation of the line is y = 0.8x - 1.4 if the slope of the line is 0.8 and line passes through coordinates (-2,-3)

Answer:
B
Step-by-step explanation:
Think of it like a quarter you got a half and half shot if getting heads or tails. meaning a 50/50 chance.
Answer: 70% or .7
Step-by-step explanation: there are 10 people total who have a brother and 7 of those people have a sister so 7/10=.7
Answer:
I think the answer is m = 0
Step-by-step explanation:
2^(-4m) = 2^(6m) set the exponent equal
- 4m = 6m Move variable to the left
- 4m- 6m = 0 collect like terms
- 10m = 0 Divide both sides by - 10
m = 0
It has to be noted that there are several ways to factor the item. One of these is shown below.
The general form of a quadratic equation is,
Ax² + Bx + C = 0
where A and B are numerical coefficients and C is the constant. If we are to express the given equation in this form,
2x² - 5x - 88 = 0
The sum of the roots, x₁ and x₂ is -B/A and the product is equal to C/A.
Sum: x₁ + x₂ = -(-5/2) = 5/2
Product: x₁x₂ = -88/2 = -44
The values of x₁ and x₂ are 8 and -11/2.
The factors are (x - 8) and (x + 11/2)
<em>ANSWERS: 8 and -11/2. </em>
