What are the x and y intercepts of the graph of -4x + 5x = -40?
Nataly [62]

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~~~

-4x + 5x = -40

y = -4x +5x + 40

y = x + 40

~~~~~~~~~~~~~~~~~~~~~~~~~~

by the look of it, after you turn that equation into slope-intercept form (y = mx + b) the intercepts are y = 40  &  x = -40

Write the equation of the line which passes through (1, 2) and with slope of −1/3
Sati [7]

Answer:

<h2>          x + 3y = 7            </h2>

Step-by-step explanation:

The equation of a line which passes through <em>(x₁, y₁)</em> and with slope of <em>m</em> in point-slope form:

                                y - y₁ = m(x - x₁)

m = -¹/₃

(1, 2)    ⇒   x₁ = 1,  y₁ = 2

Therefore,  the equation of the line which passes through (1, 2) and with slope of −1/3 in point-slope form:

y - 2 = -¹/₃(x - 1)

y - 2 = -¹/₃x + ¹/₃                     {add ¹/₃x to both sides}

¹/₃x + y - 2 = ¹/₃                     {add 2 to both sides}

¹/₃x + y = 2¹/₃                       {multiply both sides by 3}

x + 3y = 7
