Find the slope-intercept form of the line whose slope is 3 and that passes through the point (-8,9).
answer in slope-intercept form.)

Y = mx + b
( m = slope , b = y intercept )

Your answer would be "Y = 3x + 33    "

Since they already provided you with the slope all you have to do is plug in the x and y value and slope they gave you in the standard slope intercept formula and solve for b ( the y-int ) . So your equation would look
like " 9 = 3(-8) + b " . Once you solve this you'll get b = 33 . So now you know your slope and y intercept ! All you gotta do is plug it into the formula, thus you get " y = 3x + 33 "
