Hi Can Someone Please Explain How To Work This Out?!Thank you xxx
1 answer:
Solve for y, then plot (since x is the independent variable & y is the dependent variable)
x + 2y = 10
*subtract x from both sides, and divide both sides by 2 . . to get . .
y = -1/2x + 5
In slope intercept form:
y = mx + b
m = slope = -1/2 . . . the rise/run of the line . . . rise = -1 units, run = 2 units
b = y-intercept = 5 . . . where the line crosses the y-axis
(see the attached plot)

Answer:
The value of y that satisfies the system of equations is 20
Step-by-step explanation:
we have
we know that
The solution of the system of equations is the intersection point both graphs
using a graphing tool
the intersection point is (-3,20)
see the attached figure
therefore
The value of y that satisfies the system of equations is 20
