You must use the substitution method. 3x+2y=11 y=5x-1

valina [46]

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
y=4

ANSWER: x=1 and y=4 which is (1,4) as an ordered pair

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
