Answer:
e = 56
Step-by-step explanation:
Use cross multiplication.
28 * 14 = 7e
Simplify
392 = 7e
Divide each side by 7
e = 56.
Answer is C. Y intercept is 3. The slope is 2/3x.
Answer:
lines b and c are perpendicular
Step-by-step explanation:
Use slope
slope for parallel is the same
slope for perpendicular is negative reciprocal
line a slope- 1-3/-2-0 is -2/-2 or 1
line b slope- 1-4/4-6 is -3/-2 or 3/2
line c slope- 3-1/1-4 is 2/-3 or - 2/3
none are the same so none are parallel
- 2/3 is the negative reciprocal of 3/2 so lines b and c are perpendicular
When you look at the x = 0 and y = -2, that is the y-intercept since the x = 0.
Then when you look at the second one, it goes right one and up four.
As rise over run, it would be 4 / 1 or simply 4.
The slope is 4 and the y-intercept is -2
Plug it in the equation: y = mx + b. M is the slope and B is the y-intercept.
y = 4x -2
