Write equation for (-3,-6) and (2,9)

Answer

first you find slope, y2-y1 / x2-x1 which is 9-(-6) / 2- (-3), simplified to 15/5 = 3. so in the equation y = mx+b its 9 = 3(2) +b so 9 = 6+b and b = 6. so equation is y = 3x+6

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y
