never [62]3 years ago
4 0

Answer:

x=6.25\\y=-1.25

Step-by-step explanation:

3x+5y=10\\x+3y=1\\\\

Second equation times 3:

3x+9y=3

1st equation minus equation above:

-4y=7\\y=-7/4

Insert to equation:

3x+\frac{-35}{4}=10\\12x-35=40\\12x=75\\x=75/12=6.25

Use the information given to enter an equation in standard form.
Marysya12 [62]

Answer:

The equation in the standard form of the line through the given points is;

y = 3x - 17

Step-by-step explanation:

We start by getting the slope of the line;

m = (y2-y1)/(x2-x1)

m = (7-10)/(8-9) = -3/-1 = 3

The stands equation form is;

y = mx + b

m is slope, b is the y-intercept

so we have

y = 3x + b

To get b, we substitute the coordinates of any of the points

10 = 3(9) + b

10 = 27 + b

b = 10-27

b = -17

So the equation is;

y = 3x - 17
