## anonymous 4 years ago im really bad with this slope intercept form :( write an equation in slope intercept form for the line that satisfies the following condition slope 7/18 and passes through (4,-20)

1. ksaimouli

y=mx+b

2. ksaimouli

me too even iam ad toooooo

could u show me how to set it up

$m=\frac{y-y_1}{x-x_1}$ $m=\frac7{18}$ $y_1=-20$ $x_1=4$ $\frac7{18}=\frac{y-(-20)}{x-4}$ you can solve the rest right?

5. anonymous

as slope-point formula is given as, m=(y-y1)/(x-x1) m=7/18 x1=4 y1=-20 then, 7/18 = (y-4)/(x+20) 7x + 140 = 18y - 72 18y = -7x -72-140 18y = -7x -212 making its standard form as, y=mx+b y = (-7/18)x - (212) Regards, Read my Profile. :)

$y - y1 = m \times (x - x1)$ Just insert m=7/18 x1 = 4 and y1 = -20
