Answer:
y=2x-3
Step-by-step explanation:
<em>Since we know that the slope-intercept form is </em><em>y=mx+b</em><em>, we can plug in the formula with what we already know to find b!</em>
<em>In the coordinates (2,1): </em>
<em>Now, we will plug these numbers in:</em>
1=2*2+b
1=4+b
b=-3
<em>Now we can rewrite the equation since we found b:</em>
y=2x-3

Answer:
the solution is (-1, 2)
Step-by-step explanation:
Let's solve the system
(3x + 4y = 5)
(2x - 3y = -8)
using the method of elimination by addition and subtraction. Notice that if we multiply all terms of the first equation by 3 and all terms of the second by 4, y as a variable will temporarily disappear:
9x + 12y = 15
8x - 12y = -32
-----------------------
17x = - 17, so x = -1.
Replacing x in the second equation by -1, we get:
2(-1) - 3y = -8, or
2 + 3y = 8,
or 3y = 6. Thus, y = 2, and the solution is (-1, 2).
