Find the slope and the y-intercept of the equation 4x+5y=-9

a) slope=4/5 and y-intercept=-9/5

b) slope=-4/5 and y-intercept=9/5

c) slope=-4/5 and y-intercept=-9/5

d) slope=4/5 and y-intercept=9/5

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
