What is the equation of the following line written in slope-intercept form -2/3 and -1/-4? y = -11x - 7 y = -7x + 11 y = -7x - 1
Snowcat [4.5K]

Answer:

y=-7x-11

Step-by-step explanation:

Given:

The two points on the line are (-2,3) and (-1,-4).

The slope of the line joining two points (x_{1},y_{1}) and (x_{2},y_{2}) is given as:

Slope,m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Here, x_{1}=-2,y_{1}=3,x_{2}=-1,y_{2}=-4

∴ m=\frac{-3-4}{-1-(-2)}=\frac{-7}{-1+2}=\frac{-7}{1}=-7

Equation of line with a point (x_{1},y_{1}) and slope m is given as:

y-y_{1}=m(x-x_{1})

Plug in -2 for x_{1}, 3 for y_{1} and -7 for m. This gives,

y-3=-7(x-(-2))\\y-3=-7(x+2)\\y-3=-7x-(7\times 2)\\y-3=-7x-14\\y=-7x-14+3\\y=-7x-11

Therefore, the equation of the line in vertex form is y=-7x-11.

5. For Which value of x is line L parallel to line m?
laiz [17]

Answer:

x=22

Step-by-step explanation:

we know that

If line l is parallel to line m

then

130\°+(2x+6)\°=180\° -----> by supplementary angles (consecutive interior angles)

solve for x

136+2x=180

2x=180-136

2x=44

x=22
