What is an equation of a line, in point-stope form that pesses through (1,–7) and has a slope of -2/3

C)    y+7 = -2/3(x-1)

Step-by-step explanation:

You have to change the signs of the x and y coordinates...

x = 1 is the same as (x-1)

y = -7 is the same a (y+7)

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!

47
