Answer:
y=-5/2x+4
Step-by-step explanation:
5x+2y=8
2y=8-5x
2y=-5x+8
y=-5/2x+8/2
y=-5/2x+4
Answer:
<h2>x= 37/16</h2><h3>
y=199/8</h3>
Step-by-step explanation:
1....y=11+6x
-77-2x+3y=-7
replace y by ..1..
so -77-2x+3(11+6x)=-7
-77-2x+33+18x=-7
-44+16x=-7
16x=37
y=11+6x
replace x by 37/16
y=11+6*37/16
y=199/8

Answer:</h3>
y = -4x +2
<h3>
Step-by-step explanation:</h3>
The slope-intercept form of the equation for a line is conveniently found from the point-slope form. In either case, you need to know the slope. That is ...
... slope = m = (change in y)/(change in x)
For the first two points, the slope is ...
... m = (-6 -(-2))/(2 -1) = -4
Using the point-slope equation for slope m and point (h, k) written as ...
... y = m(x -h) +k
we can substitute m = -4 and (h, k) = (1, -2) to get ...
... y = -4(x -1) -2
... y = -4x +2 . . . . . . . simplify
The answer is all of the above. Hope this helps!
