Slope-intercept <br><br> X-intercept = 3 , y-intercept = 3
Mama L [17]

Answer:

y=-1x+3

Step-by-step explanation:

Slope intercept form: y=mx+b

x intercept (3,0)

y intercept (0,3)

slope= \frac{y2-y1}{x2-x1} = \frac{3-0}{0-3} =\frac{3}{-3} =-1

start subbing in numbers from one of the points. I'm using hte x intercept so it would be (0,3). m = slope

y=mx+b

3=-1*0+b

3=0+b

b=3

so now that you know what b and the slope is,

y= -1x+3
