Write in slope intercept form, then convert to standard form Slope=1, y-intercept=-3​
Viktor [21]

Slope = 1

y-intercept = -3, which can be expressed as (0,-3).

y - y_1 = m(x - x_1)

y -(-3) = 1(x - 0)

y + 3 = x

The slope-intercept form is

y = x - 3.

The standard form is Ax + By = C.

y = x - 3

3 = x - y

Done.

A dozen bran muffins cost $9.48. Which equation represents the cost, y, of x muffins
swat32

Answer:

12y+9.48x=0

Step-by-step explanation:

Note dozen means 12 in mathematics

So 12 muffins cost $9.48

X muffins cost $y

So let's cross multiply

12×y=9.48×x

12y=9.48x

Substrate 9.48x from both sides

12y-9.48x=0

So the final equation is 12y-9.48x=0
