1) through: (-2,4), slope = 0<br> how you do this??

elena-s [515]

Answer:

y = 4

Step-by-step explanation:

I assume you want to find the slope-intercept form of the given information.

We are given the slope and a point, so we can find the y-intercept.

y = 0x + b

4 = 0(-2) + b

4 = 0 + b

4 = b

Put everything we know/solved for back into the formula [ y = mx + b ]

y = 4

Best of Luck!

What is the equation of the line that passes through the points (−2, 1) and (1, 10)? 3x − y = −73x − y = −53x − y = 5x + 3y = −5

djyliett [7]

The two point formula :

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

The points are (-2, 1) and (1, 10)

Using the formula above :

$\begin{gathered} y-1=\frac{10-1}{1-(-2)}(x+2) \\ y-1=\frac{9}{3}(x+2) \\ y-1=3(x+2) \\ y-1=3x+6 \\ -3x+y=6+1 \\ -3x+y=7 \\ 3x-y=-7 \end{gathered}$

The answer is 3x - y = -7

A certain motorcycle manufacturer has been building motorcycles for 98 years. Over that period, production has increased steadil

Reika [66]

Answer: The fraction would be 0.53.

Step-by-step explanation:

Since we have given that

$r(t)=A.(1.05)^t$

where, A is the constant initial production rate

t is the time.

For 98 years, the production rate in motorcycles per year would be

$r(98)=A.(1.05)^{98}\\\\r(98)=A.119.27$

For 13 years, the production rate in motorcycles per year would be

$r(98-13)=r(85)=A.(1.05)^{85}\\\\r(85)=A.63.25$

So, the fraction of their total production was built during the last 13 years would be

$\dfrac{r(85)}{r(98)}=\dfrac{63.25}{119.27}=0.53$

Hence, the fraction would be 0.53.
