Question

Find the equation of the line between (-9, -3) and (-2,6) in slope
intercept form

Answer 1

Answer:

Step-by-step explanation:

so use the change formula: Δy/Δx

since you have two point the formula would be like this:

ysub2-ysub1/ xsub2-xsub1

(-9,-3)(-2,6)

x1,y1  x2,y2

6-(-3)/-2-(-9)

9/7= slope

slope intercept form is y=mx+b

so i chose (-2,6)

6=-2(9/7)+b

6=-18/7+b

42+18=7b

60/7=b

now put everything together:

y=mx+b

y=9/7+60/7
