Solve the linear equation for –y. This will put the equation in slope- intercept form. Then find the slope and the y intercept of the line with the equation.

1) put equation in standard form
y = mx + b
where m is slope, b is y intercept
2) y = - 2/9x
Thus, the slope is -2/9
and the intercept is 0
For your other part of the question, just multiply -1 times both sides to solve for -y.
-y = 2/9x
Tada!

one answer may be to adhere to the Slope-intercept type of a line. the line with slope m and y-intercept b has an equation of the form y = mx + b you stated you had a y-intercept of three so as which will take the concern of b in our y = mx + b equation all it is left now might want to be to calculate the slope of the line, denoted with the help of the letter 'm' in our equation. stated in words you may want to declare the slope of a line is the strengthen over run - how plenty the line rises divided with the help of how plenty it runs around the x axis. to artwork it out w/ the numbers we will use the aspects out of your question. if the line passes with the help of two on the x-axis then the coordinates for that ingredient may be (2,0) If the line also passes with the help of three on the y-axis then the coordinates for that ingredient may be (0,3) each and each of those aspects is largely interior one of those (x,y) upward thrust/run .... enable's first stumble upon out how plenty the line rises in accordance with those 2 contraptions of issues, (2,0) and (0,3) the strengthen relies on the excellence between the y coordinates of those 2 aspects and the y values are 0 and three so, 0-3 = -3 (detrimental 3) and the run relies on the excellence between the x coordinates or (2 and 0) 2 - 0 = 2 so the slope is -3/2 it is the cost for m substituting the cost for b and m into the ingredient slope formula we get y = ( -3/2)x + 3 it truly is your answer. you may also make sure your answer with the help of plugging in straightforward values for x then y. enable x = 0, then your equation will develop into y = (-3/2) x 0 + 3 y = 0 + 3 y = 3 so, even as x is 0, y is 3 it truly is strictly what you stated it replaced into on your unique question. we are in a position to do the similar aspect with the help of putting y equivalent to 0 then, y = (-3/2)x + 3 0 = (-3/2)x + 3 (3/2)x = 3 3x = 6 x = 2 it truly is also what you gave as an unique value, i.e., even as y = 0 then x = 2. y = mx + b ...you'll run into that one plenty :)

-y=2/9x
the slope is -2/9
the intercept is 0
