What is the slope of the line that passes through the points (26, 7) and (-39, 12)?

-1/13

Step-by-step explanation:

The slope of a line is calculated as rise/run.

The rise is the difference in y-values, and the run is the difference in x values

slope= y₂ - y₁/x₂ - x₁

let (26 , 7) be (x , y) and (-39 , 12) be (x₂, y₂)

slope= (12 - 7)/ (-39 -26)

        = 5/-65

reduce the fraction to get -1/13

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
