Answer:
I think the answer would be -5
Step-by-step explanation:
Sorry if its wrong
Answer:
Step-by-step explanation:
The slope-intercept form of equation of a linear function:
m - slope
b - y-intercept
We have the slope m = 4/5 and the y-intercept b = -6. Substitute:
Answer:
20.4
96
Step-by-step explanation:
The value of 5x² - 11x + 18 is
5(2.4)²-11(2.4) +18 = 5(5.76) -26.4+18
= 28.8 -26.4+18 = 20.4 (when x = 2.4)
and 5(-3)² -11(-3) +18 = 45+33+18 = 96
(when x = -3)
4x - 3y - 7 = 0
-3y = -4x + 7
y = 4/3x - 7/3....slope here is 4/3
A. a parallel line will have the same slope
y = mx + b
slope(m) = 4/3
(-2,1)...x = -2 and y = 1
sub and find b, the y int
1 = 4/3(-2) + b
1 = -8/3 + b
1 + 8/3 = b
3/3 + 8/3 = b
11/3 = b
so ur parallel line is : y = 4/3x + 11/3
B. A perpendicular line will have a negative reciprocal slope. To get the negative reciprocal of a number, u flip the number and change the sign. So our perpendicular line will need a slope of -3/4
y = mx + b
slope(m) = -3/4
(-2,1)...x = -2 and y = 1
sub and find b, the y int
1 = -3/4(-2) + b
1 = 3/2 + b
1 - 3/2 = b
2/2 - 3/2 = b
-1/2 = b
so ur perpendicular equation is : y = -3/4x - 1/2
Answer:
y= 2× +4
Step-by-step explanation:
Slope intercept form y = mx +b
4x -2y = -8
-2y = -4x-8
y = 2x +4
slope = 2x
y intercept = 4
