If you know that a line has a slope of 2/3 and a y-intercept of 7, what is the equation for that line in slope-intercept form?

the equation for a line is y = mx+b

 m = slope

b = y intercept

 you know the slope is 2/3 and the y intercept is 7 so just replace them in the equation:

 y =2/3x +7

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
