Question

How do you find the slope of the line passing through (-11,4), (-4, 11)?

Answer 1

`"slope" =1`

Explanation:

`"to calculate the slope use the "color(blue)"gradient formula"`

`color(red)(bar(ul(|color(white)(2/2)color(black)(m=(y_2-y_1)/(x_2-x_1))color(white)(2/2)|)))`
where m represents the slope and `(x_1,y_1),(x_2,y_2)" are 2 points on the line"`

`"the 2 points are "(x_1,y_1)=(-11,4),(x_2,y_2)=(-4,11)`

`rArrm=(11-4)/(-4-(-11))=7/7=1`
