Answer:

y = 1/2x +7

Step-by-step explanation:

I like to start with the 2-point equation for a line.

y = (y2 -y1)/(x2 -x1)(x -x1) + y1

y = (9 -8)/(4 -2)(x -2) +8 . . . . . fill in point values

y = 1/2(x -2) +8 . . . . . simplify a bit

y = 1/2x +7

How do u determine the equation of the line through each pair of points in slope-intercept form (y=mx+b). (3,0) and (2,4) (-6,3)

Answer:

Y =-4X +12

Y =-0.625X -0.75

Step-by-step explanation:

(3,0) and (2,4)....

x1 y1 x2 y2

3 0 2 4

(Y2-Y1) (4)-(0)= 4 ΔY 4

(X2-X1) (2)-(3)= -1 ΔX -1

slope= -4

B= 12

Y =-4X +12

~~~~~~~~~~~~~~~~~

(-6,3) and (2,-2)

x1 y1 x2 y2

-6 3 2 -2

(Y2-Y1) (-2)-(3)= -5 ΔY -5

(X2-X1) (2)-(-6)= 8 ΔX 8

slope= - 5/8

B= - 3/4

Y =-0.625X -0.75

Given the following system of equations: -4x+8=16, 2x+4y=32 what action was completed to create this new equivalent system of eq

castortr0y [4]

The equation (1) is divided by 2 to create new equivalent system of equations.

Step-by-step explanation:

The given systems of equations are:

$-4x+8y=16\,\,\,(1)\\2x+4y=32\,\,\,(2)$

Considering 8y instead of 8 in eq(1)

We need to identify what action was completed to create this new equivalent system of equations? $-2x+4y=8, 2x+4y=32$

Comparing given equations we came to know that equation(1) is divided by 2 to get the new equation i.e

$-4x+8y=16\\Divide\,\,by\,\,2:\\-2x+4y=8$

While second equation is same as given.

So, The equation (1) is divided by 2 to create new equivalent system of equations.
