Question

What is the solution for line one: y=-2x+1 line two: -2x-3

Answer 1

The slope-intercept form is

y=mx+b

, where m is the slope and b is the y-intercept.

y=mx+b

Find the values of

m

and

b

using the form

y

=

m

The slope of the line is the value of

m

, and the y-intercept is the value of

b

.

Any line can be graphed using two points. Select two

x

values, and plug them into the equation to find the corresponding

y

values.

I'm so sorry it layed out like this my computer is being st00pid

Answer 2

I don’t know what’s being asked in particular yet:
y=-2x+1
y-intercept= 1
x-intercept= 1/2
graphing: starting at the y axis at +1 , go down 2 units and then one unit to the right.

y=-2x-3
y-intercept= -3
x-intercept= -3/2
graphing: starting at the y axis at -3 , go down -2 units and one unit to the right.
