Point slope form for (-1,-4) and (2,1)

y+4=5/3(x+1)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(1-(-4))/(2-(-1))

m=(1+4)/(2+1)

m=5/3

y-y1=m(x-x1)

y-(-4)=5/3(x-(-1))

y+4=5/3(x+1)

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
