Graph -2x=y +3 using the slope-intercept form What is that?

Answer 1

The standard equation for slope-intercept form is y=mx+b. m is the slope and b is the y-coordinate of the vertical (y) intercept

-2x=y+3 Original equation

y=-2x-3 Rewritten in S-I form

m= -2, b= -3

This means that the graph of the funtion is a line through the y-axis at the point (0, -3) with a slope of (-2)

Answer 2

Arrange the equation into standard form such as:

y = mx + b
where m is the slope
b is a constant that when x is set to zero is equal to what is called the y intercept.

For your standard form

y = -2x -3
Set x = 0 so y = 3 the y intercept is -3.

Make a Column of x values from say 1 to 10 or 1 to 100 if you want....then make a column next tot he x column of the Y values produced by the equation. You can graph these manually by plotting the (x,y) pairs on graph paper. If you have a graphing calculator I am pretty sure you can just tpe in the equation in the standard form and it will graph it over whatever limits of x you want.

Answer 3

Slope intercept form just means:
Get the y intercept. Thats when x = 0, so y = -3.
Get the slope. Thats -2.
So, draw a line from -3 on the y axis, that goes across 1 and down 2.

Answer 4

y = mx + C is an equation for straight line. This means that if your x and y variable fall on a straight line when you make a cross plot between x and y. so the line forming this relationship has a slope called m and you need to add a constant C so that the point y falls on the straight line (its called regression)...

In your case, m here is -2 and C is -3 so if you want to estimate y when x=1 it would be
y = -2 multiplied by 1 - 3 = -2 - 3 = -5

Answer 5

y = mx + C is an equation for straight line. This means that if your x and y variable fall on a straight line when you make a cross plot between x and y. so the line forming this relationship has a slope called m and you need to add a constant C so that the point y falls on the straight line (its called regression)...

In your case, m here is -2 and C is -3 so if you want to estimate y when x=1 it would be
y = -2 multiplied by 1 - 3 = -2 - 3 = -5

Remember the assumption is that y varies linearly to x.

Answer 6

Y=mx+b M is slope so jsut re arange your formula moving the three to the other side and then solving for m

Answer 7

y=-2x-3
slope=-2 and y intercept=(0,-3)
whenn y=0
-2x=3
dividing by -2
x=-3/2
so x intercept (-3/2,0)
using the points(-3/2,0) and (0,-3)
the line can be drawn

Answer 8

standard form is y=mx+b
subtract 3
y= -2x-3
slope is -2
y-int is -3

Answer 9

it be comes y= -2x- 3
you should be able to handle it yourself from there on
