Idont know what im doing! explain your answer, !

y = 1/2 x -4

Step-by-step explanation:

When we have a point and a slope, we can use the point slope form of an equation

y-y1 = m(x-x1)

y--2 = 1/2(x-4)

y+2 = 1/2x -2

Subtract 2 from each side

y+2-2 = 1/2x -2-2

y = 1/2 x -4

This is in slope intercept form where is the slope is 1/2 and the y intercept is -4

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
