Answer:
y = -1/2x +5
Step-by-step explanation:
Slope-intercept form is ...
y = mx + b
Matching this to the equation you have, you see that ...
m = -2/4 = -1/2
b = 5
The equation is already in slope-intercept form. The fraction that is the slope can be reduced, but that is not essential to the form.
247- 538 = -291
If you line them up in that order 247 you'll have to borrow. Your answer would be -291
-538
The only way to not get -291 is to flip the two numbers.
Let's use the "elimination by addition/subtraction" method to solve this system for x and y.
<span> -8x=72-16y
4x=-92+16y <= Mult. all 3 terms by 2: 8x = - 184 + 32y
Now combine the following, column by column:
</span><span> -8x= 72-16y
</span>8x = - 184 + 32y
-----------------------
0 = -112 + 16y. Solving for y, 16y = 112, and y = 7.
Now subst. 7 for y in either of the original equations and calculate x:
<span>4x=-92+16(7) => 4x = -92 + 112 = 20. Then x = 5.
Solution is 5, -7 (or, better written) (5, - 7).</span>
