Write the equation of the line in fully simplified slope-intercept form.
hoa [83]

Answer:

y = -x+3

Step-by-step explanation:

Slope intercept form =>  y = mx+b

To find 'm', the slope, pick 2 coordinates.

(0,3)

(2,1)

Use this equation to find the slope using these 2 coordinates: (y1 - y2)/(x1 - x2)

(3 - 1)/(0 - 2) = -1

m = slope = -1

'b' is the y-intersept, or the point when a line passes through the y-axis. That's (0,3).

b = y-intercept = 3

<em>So the equation will be y = -1x + 3, or y = -x + 3</em>

2y-4x=-12 what is the slope intercept
SpyIntel [72]
So you have yo turn it into the correct form first so you add 4x to both sides and come out with 2y=4x-12 them you divide each side by 2 because you have to have to by itself and you come out with y=2x-6 so the slope is 2x and the y intercept is -6

A mile has 5,280 feet.

Divide 18,472 by 5,280.
18,472 / 5,280 = 3.5

18,472 feet is about 3.5 miles.
