Find an equation in slope-intercept form passing through the points (2,5) and (7,-3).

M=(-3,-5)/(7,-2)

M=-8/5 IS THE SLOPE

[Y=MX+B]

5=-8/5*2+B

5=-16/5+B

5+16/5=B

(25+16)/5=B

41/5=B THE Y INTERCEPT

Y=-8X/5 +41/5

HOW WOULD I SHOW A GRAPH ON THIS PROBLEM?

your slope is incorrect

slope = (-2+5)/(7+3) = 3/10

so y = (3/10)x + b

using (-3,-5)

-5 = (3/10)(-3) + b

-50 = -9 + 10b

b = -41/10

y = (3/10)x - 41/10

I'm not sure of your question.

Do you know how to graph an equation?

Is it because there are fractions?

If because of fractions, convert to decimals and estimate as best you can.

Your equation would be,

y = -1.6 x + 8.2
