Isolate the variable by dividing each side by factors that don’t contain the variable
Exact form:
x= - 13/3
Decimal form:
x= -1.857142
Mixed number form:
x=- 1 6/7
42x + 28y......the GCF is 14...so factor out 14
14(3x + 2y) <==
Y = 1/2x - 5
We know the slope to be 1/2 because lines that are parallel have the same slope. Then we can solve using slope-intercept form and the known point.
y = mx + b ----> Input known values
-2 = (1/2)(6) + b ---> Multiple
-2 = 3 + b ----> Subtract 3 from both sides
-5 = b
Now we can use the y-intercept found and the slope to write the equation above.
Just put into a calculator.
2*4.1/1
= -2*4.1 = -8.2
