Convert this into slope intercept from & provide its slope 5x-2y=4

Elden [556K]

Slope Intercept Form: y=mx+b
m= slope
b= y-intercept

5x - 2y= 4
subtract 5x from both sides

-2y= -5x + 4
divide both sides by -2

y= (-5x + 4)/-2
negative divided by negative equals a positive; positive divided by negative equals a negative

y= 5/2x - 4/2
simplify where possible
y= 5/2x - 2

ANSWER:
Slope Intercept Form: y= 5/2x - 2
Slope: 5/2

Hope this helps! :)

Solve by using substitution<br>-7x-2y=-13 and x-2y=11

netineya [11]

$\left \{ {{-7x-2y=-13} \atop {x-2y=11}} \right. \\\\ \left \{ {{-7x-2y=-13} \atop {x=11+2y}} \right.\\\\
Substitute\ second\ equation\ into\ the\ first\ one:\\\\
-7(11+2y)-2y=-13\\
-77-14y-2y=-13\\
-77-16y=-13\ \ \ |Add\ 77\\
-16y= 64\ \ \ |Divide\ by\ -16\\
y=-4\\\\x=11+2y=11+2*(-4)=11-8=3\\\\ \left \{ {{y=-4} \atop {x=3}} \right.$

Literal equations 2x-3y=8 solve for y

jeka94

2x-3y = 8

Add 3y on both sides

2x = 8 + 3y

Subtract 8 on both sides

3y = 2x - 8

Divide 3 on both sides

<span> $y= \frac{2}{3}x- \frac{8}{3}$ </span>
