Find the equation of the line that passes through (4,8) with slope -3. write in slope intercept form

you have to put it in Point Slope Form.

ABOUT POINT SLOPE FORM:

ABOUT PROBLEM:

y - Y1 = m(x - X1)

y - 8 = -3(x - 4) --- IN Point Slope Form

If you want to put it in Slope Intercept Form, you can solve it:

y - 8 = -3(x - 4)

y - 8 = -3x + 12

  + 8          + 8

y = -3x + 20 --- IN Slope Intercept Form

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!
