Determine the slope and y-intercept from the following equation: 4x + y = -10

Mathematics
1 answer:
egoroff_w [7]4 years ago
3 0

Answer:

Answer D: Slope: 4 y-intercept: -10

Step-by-step explanation:

The answer is D because in the slope-intercept equation(y=mx+b) m=slope and b=y-intercept. This equation is not in the correct order but the slope is 4 because it is where the m would be and it's next to the x. The y-intercept is  -10 because it's where the b would be in this equation, it's by itself, and you can see the y separate from any numbers.

Hope this makes sense and helps!!!!

2x - 3y = 45 and x + y = 10 what is the x - value of the solution of the system
abruzzese [7]

Answer:

x=15

Step-by-step explanation:

This is a simultaneous equation

2x-3y=45 ------------------------------ equation i

x+y=10    -------------------------------equation ii

from equation ii

x+y=10

make x the subject of the matter

we have,

x=10-y

in equation i

substitute x for 10-y

2x-3y=45----------------------i

since x=10-y

we have,

2(10-y) - 3y=45

20-2y=3y=45

collect like terms

-2y-3y=45-20

-5y=25

divide both sides by -5

we have y=-5

substitute y for-5 in equation i

x+y=10

x+-5=10

collect like terms

x=10+5

x=15

therefore

x=15
