Answer:

y=-4/3x-8/3

Step-by-step explanation:

Use the slope formula y2-y1/x2-x1

Finding the slope, 4-(-4)/-5-1 = 8/-6 = -4/3

y=-4/3x + b

Substituting,

-4=-4/3+b

-12/3+4/3=b

b=-8/3

y=-4/3x-8/3

So starting with the question which is
4x-3=2x+13
All you have do is subtract 2x from 4x which is 2x
So now the equation will become
2x-3=13
Minus 3 on both sides So 2x is left over
2x=16
X=8

LUCKY_DIMON [66]

Answer:

y = x - 3

Step-by-step explanation:

Equation of line in slope point form is given as:

y - y_1 = m(x - x_1)

$y - y_1 = m(x - x_1) \\ y - 2 = 1(x - 5) \\ y - 2 = x - 5 \\ y = x - 5 + 2 \\ y = x - 3 \\$

What is the solution set to the following system?<br> X+y=4<br> X^2+y^2=16

faltersainse [42]

X+y = 4, -----> y=4 - x
x² +(4-x)² =16
x² +16-2*4x+x² =16
2x² - 8x = 0
x(2x-8) = 0
2x-4=0, 2x=8, x=4
x=0 or x=4

If x=0, y=4-x=4-0=4.
If x=4, y= 4-x=4-4=0.

(0,4) or (4,0)

Check
x² +y² =16
For (0,4)
0²+4² =16
16 =16 True

For (4,0)
4² +0²=16
16=16 True

Answer (0, 4) and (4,0).
