Plug in y=5x-1 for y in 3x+2y=11

3x+2(5x-1)=11
3x+10x-2=11
13x=13
x=1

plug x=1 to y=5x-1 to find y

y=5(1)-1
y=5-1

Calculate the slope of a line that passes through the points (-4,7) and (-1,3)
zmey [24]

Answer:

The answer is

-  \frac{4}{3}  \\

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-4,7) and (-1,3)

We have

m =  \frac{3 - 7}{ - 1 -  - 4}  =  \frac{ - 4}{ - 1 + 4}  =   -  \frac{4}{3}  \\

We have the final answer as

-  \frac{4}{3}  \\

Hope this helps you
