Question

What is the slope-intercept form of the following equation? What is slope and the y intercept? 8x + 2y = 14

Answer 1

slope-intercept form: y=-4x+7 Slope= -4 y-int.= 7

Explanation:

y-mx+b

8x + 2y = 14

move x to opposite side of = (makes x negative)

2y=-8x+14

y needs to be alone so divide the entire thing by 2

y=-4x+7 this is in y=mx+b form.

y=mx+b: your m is your slope and b is your y-int.

Answer 2

m

=

4

Explanation:

Given -

8

x

−

2

y

=

14

It is in the form

a

x

+

b

y

=

c

If a linear equation is in this form, then -

It slope is

−

a

b

In our case, we shall use this formula
