What is the equation of a line that passes through points (0, 4) and (-4, -8)?

The answer is D. you know that the equation must end in +4 as the yintercept is at four (y=4 when x=0)
then you can work out that it is 3x because when x changes by -4, y changes by -12, which is three times as much.
Hope this makes sense!

Slope = (-8 - 4)/(-4 -0) = -12/-4 = 3

y-intercept so b = 4

equation: y = 3x + 4

answer: <span>C. y = 3x + 4</span>

6. No, the conclusions wrong because 20 out of 50 peoples favourite is drawing which means 20/50 which equals 0.4 times 100 which is 40% not 60%

7. Yes, the conclusion is right because 5/50 is equal to 0.1 times 100 which is 10%

How many soulutions does the system of equations have x-3y=15. and 3x-9y=45

Irina-Kira [14]

Answer:

<h2>Infinitely many solutions</h2>

Step-by-step explanation:

$\left\{\begin{array}{ccc}x-3y=15\\3x-9y=45\end{array}\right\\\\\text{Divide both sides of the second equation by 3}\\\\\dfrac{3x}{3}-\dfrac{9y}{3}=\dfrac{45}{3}\\\\x-3y=15\\\\\text{We received the same equation as the first.}\\\\\bold{CONCLUSION}\\\\\text{The system of equations has infinitely many solutions.}$

$\left\{\begin{array}{ccc}a_1x+b_1y=c_1\\a_2x+b_2x=c_2\end{array}\right\\\\\text{If}\ a_1=a_2,\ b_2=b_2,\ c_1=c_2,\ \text{then the system of equations}\\\text{ has infinitely many solutions}\\\\\text{If}\ a_1=a_2,\ b_1=b_2,\ c_1\neq c_2,\ \text{then the system of equations}\\\text{has no solutions}\\\\\text{Other the system of equations has one solution.}$
