Answer:
<em>y = -2x + 25/2</em>
Step-by-step explanation:
Slope intercept form is y = mx + b.
You must solve the equation for y.
4x + 2y = 25
Subtract 4x from both sides.
2y = -4x + 25
y = -2x + 25/2
Look at the picture.
We have the similar triangles (AAA). Therefore the lengths of the sides are in proportion:
<em>multiply both sides by 8</em>
Reorder the terms: 6.25 + -5y + y^2 = -14 + 6.25
Combine like terms: -14 + 6.25 = -7.75 6.25 + -5y + y2 = -7.75
Factor a perfect square on the left side: (y + -2.5)(y + -2.5) = -7.75
Can't calculate square root of the right side (negative). The solution to this equation could not be determined.
none of those are right it is 4 because there is no x behind the 4.
