Answer:
-4(8x-7)/7
Step-by-step explanation:
1. Simplify Term.
-8/7 (4x) - 8/7 * -3 + 4/7
-32x/7 - 8/7 * -3 + 4/7
-8/7 * 3
-32x/7 + 24/7 + 4/7
2. Simplify Term.
−
32
x * 24 + 4 divided by 7
-32x + 28 divided by 7
4(-8x + 7) divided by 7
4(-(8x) + 7) divided by 7
3. Rewrite 7 as -1(-7)
4(-(8x) - 1(-7)) divided by 7
4(-(8x - 7)) divided by 7
4. Rewrite -(8x - 7) as -1(8x - 7)
4(-1(8x - 7)) divided by 7
-4(8x - 7)/7
Y + -4 = 9 (this means y plus negative 4 equals 9)
y -4 = 9
+4 +4
y = 13
To find the equation of a perpendicular line, you first need to find the negative reciprocal of the slope given. The slope is -1/3, so the slope of the perpendicular line will be 3
Now we just need to find the y intercept using the point (3, 2) and you can plug the coordinates in and then solve for b. Let's see what that looks like.
y=3x+b
2=3*(3)+b
2=9+b
-7=b So now we know the y-intercept and slope. We just put them together now
y=3x-7
