Y intercept means the y-coordinate of the point where the graph crosses the y-axis.
Given equation is:
Let x be 0, as at the y-intercept point, the x-coordinate of that point is always 0.
y=
Slope-intercept form is y = mx + b
where m is the slope of the line and b is the y-intercept of the line {the number without a variable}
-2x+6y = 5
6y = 2x+5
y=
Hence, slope is
a)
30.65^2/(2*5.15)=91.2061
d=91.2061
b)i)90
ii) Mathswatch is critical of anything apart from it's system so I dont know what the answer is for this one
Answer:
The answer is B.
Step-by-step explanation:
When Elimination method is applied, you have to eliminate one of the variables from both equations. Firstly, both equations contain 4y so you can subtract it :
Next, you have to substitute x = 5 to any equations. I will choose to put in (2) :
Therefore, put your answer in coordinate form :
Answer:
is the .3 supposed to be there? if not then its ×=2.3
