3. y=37x+11y=37x+11 -3x + 7y = 13 part a: convert the second equation to slope-intercept form. show your work! part b: determine whether or not the graphs of the lines are parallel. explain how you know.

We are given first equation y=x+11.

Second equation is -3x + 7y = 13.

Part A: We need to convert that second equation in slope-intercept form y=mx+b.

In order to convert it in slope-intercept form, we need to isolate it for y.

-3x + 7y = 13

Adding 3x on both sides, we get

-3x+3x + 7y = 3x+13

7y = 3x +13.

Dividing both sides by 7, we get

7y/7 = 3x/7 +13/7.

Slope for first equation y=3/7 x +11 is 3/7 and slope of second equation y= 3/7 x + 13/7 is also 3/7.

Slopes are same for both equations.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

i honestly dont know
