Write the equation 2x-5y=20 in slope intercept form

Step-by-step explanation:

2x-5y=20

Making y the subject

-5y = -2x + 20

Dividing by -5

y = -2/-5x + 20/-5

y = 2/5x - 4

So comparing with y = mx + c

Slope m = 2/5

Intercept c = -4

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

step-by-step explanation:

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
