Question

Use intercepts to graph the line described by the equation.

2y = −10x − 20

Answer 1

Answer:

First, put it into slope/intercept form so you can see what you've got.

"Slope/intercept form" is      y = everything else  .

So that means you have to take the equation you have and "solve it for 'y' ".

2y - 10x = 20

Add  10x  to each side:        2y = 10x + 20

Divide each side by  2 :        y  =  5x  +  10

And that's exactly the information you need to graph it.  On your graph,

mark a little dot on the y-axis at  10, and draw a line through that dot

with a slope of  5.

Answer 2

Answer:

y = 5x -10

Step-by-step explanation:

Slope intercept :  2y = -10x - 20    divide everything by 2  = 2y / 2 = - 10x/2  - 20/2 =   y = 5x-10

y-axis at  -10, and draw a line through that dot

with a steep slope of 5 as we know ascending slope is 5/1 = y/x = 5
