I need help on this problem

Vaselesa [24]

The answer is y=3/2x+3

to figure it out:
1. you need to first find the slope of the two points.
3-0/0-(-2)
2. then put them into slope intercept form: y=mx+b. m being your slope and b being your y-intercept.

I need help,I need to use substitution but I don't know how

If $y=x+6$ and $y=-2x-3$ , then you can replace $y$ in either equation with the equivalent expression given by the other equation. In this case, you have

$x+6=-2x-3$

and you can solve for $x$ .

$x+2x+6-6=-2x+2x-3+6\implies3x=3\implies\dfrac{3x}3=\dfrac33\impliesx=1$

Then $y=1+6=7$ .

For the second system, you can write

$5x-y=-5\implies 5x-5x-y=-5-5x\implies-y=-5-5x$

$\implies-(-y)=-(-5-5x)\implies y=5+5x$

Then substitute this into the second equation and you get

$3x-6(5+5x)=24\implies3x-30-30x=24\implies-27x-30+30=24+30$

$\implies-27x=54\implies x=2$

so that

$y=5+5(2)=15$

(1,9) and (6, 34)<br> Equation:

Sholpan [36]

Answer:

y= 5x+4

Step-by-step explanation:

find the slope 34-9/6-1 = 25/5 = 5

then use y-y1= m (x-x1)

y- 9 = 5(x-1)

y-9 = 5x -5

y = 5x +4
