Find an equation of the line that (a) has the same y -intercept as the line y + 5x + 9 = 0 and (b) is parallel to the line - 3x
kap26 [50]

Equation of required line is:

y = \frac{3}{4}x-9

Step-by-step explanation:

First of all we will convert both equations in slope-intercept form

y + 5x + 9 = 0

Subtracting 5x from both sides

y+9 = 0-5x\\y+9 = -5x

Subtracting 9 from both sides

y+9-9 = -5x-9\\y = -5x-9

The y-intercept is -9.

Other equation is:

- 3x + 4y = 3

Adding 3x on both sides

-3x+3x+4y = 3x+3\\4y=3x+3

Dividing both sides by 4

\frac{4y}{4} = \frac{3x+3}{4}\\y = \frac{3}{4}x+\frac{3}{4}

As the required line has y-ntercept of line y + 5x + 9 = 0

So,

b = -9

And

The line is parallel to second line, so the slopes of both will be equal

m=\frac{3}{4}

Slope-intercept form of line is:

y=mx+b

Putting values of b and m

y = \frac{3}{4}x-9

11x + 2y = 68 & 5x + y = 13
matrenka [14]

Answer:

i hope its correct

Step-by-step explanation:

11x + 2y=68 ------------1

5x+y=13 ------------2

y= 13-5x. ------------3

put 3 into 1

11x +2(13-5x) =68

11x +26 -10x =68

x=42

put x =42 into 2

5(42) +y =13

210+y=13

y=13-210

y=197
